NEW EDIT... Now the final question... do I get the XFX or EVGA version of the 9800GTX+?????


OK,

I'm currently running two EVGA 7950GT cards in SLI on my Asus P5N32-E SLI (680i)

Just wondering a couple of things as I can't seem to find the answer on google...

I know the 8800GT and 9800GT are pretty much the same thing... but for just a few $$ more I may as well get the 9800GT.... or am I wrong on this?

Anyway...

Would one 8800GT or 9800GT perform better than my two 7950GT cards in SLI?... or would I need to get two 8800GT / 9800GT cards to beat my 7950GT cards??

Also, I'm currently running with an Antec TruePower Trio 650w PSU... if I went with two 9800GT cards in SLI... would I need to upgrade that as well?... currently my PSU is running the 7950GT cards in SLI with no issues.
August 5, 2008 5:50:37 PM

forgot to ask...

My wife is currently running two XFX 8600GTS cards in SLI... would a single 8800GT or 9800GT card beat her setup as well... or would she need to run in SLI with the 88/98 as well?

Also, forgot to say that she has the same PSU as me and is running her 8600GTS cards without any issues.

Thanks for any help,
TK.

Well I can say with certainty that a single 88/9800GT will beat your wifes setup, and Im confident that it would best yours as well, just not by as large of a margin.

As to power requirements, without knowing the rest of your components its hard to say, but generally speaking your Antec units should be able to keep up with SLied 8800/9800GT setups.

im pRETTY sure 8800gt/9800gt is the same thing... i've heard of absolutely no difference except the name as of now
August 5, 2008 6:29:29 PM

looks like one 8800gt is on par with dual 7950gt's. however, the big difference will be in games that don't scale well in sli. i went from a single 7950gt to a single 8800gt and it was a pretty big difference. games play much smoother now and at higher graphic settings.
August 5, 2008 6:31:18 PM

Megagamer3 i'm not sure if you've noticed but those charts haven't been updated in months/years.

+1 for the 9800gt upgrade (even though its just a rebranded 8800gt)
August 5, 2008 6:34:35 PM

Sound good... thank you for the fast replies.

Basically, I've been thinking it's time to upgrade both our computers... but really don't want to spend the money on 4 new cards.

I was hoping to just get two 9800GT cards and then upgrade both to SLI again alittle later.

should I worry about running 9800GT cards in SLI with our current PSUs??

lastly, anyone have any measurements on the length of the 9800GT? Is it as long or longer than the 7950GT? I'm already low on space, lol.
August 5, 2008 6:58:48 PM

Again thanks for the replies...

After speaking with the wife, it sounds like we'll upgrade to a single card for now and then add the others for SLI in month or so.

Last questions I need answered before we jump...

1) what's the performance difference between 9800GT and 9800GTX+... is it worth an extra $50 per card to get the GTX+

2) will our current Antec TruePower Trio 650w PSUs be enough to run dual SLI with 9800GT or 9800GTX+

3) have seen the BFG Tech Overclocked 9800GTX+... is it worth it? (I think I remember it likes to lock up, any thoughts??)

Your PSU is fine for 8800GT SLI or 9800GT SLI, no worries.

The 9800GT is 9 inches long. The 7950GT is 7.8" long (at least the PNY)
http://www.nvidia.com/object/product_geforce_9800gt_us.html
If you don't have the extra 1.2" get an Antec 900.

BTW, the 9800GT has 112 stream processors, just like the 8800GT, so I think eklipz is right, they're basically the same thing.

The GTX+ has 128 processors instead of 112. Expect 14% more speed based on that. It's based on 55nm tech, which should allow higher clocks, so expect some speed improvement from that too, but not a lot. I'm guessing the 9800GTX+ will be up to 25% faster. No idea if that's worth $50 to you, you decide.
August 5, 2008 7:14:30 PM

The difference in the 9800 GT and 8800 GT is Open GL2 vs. Open GL 2.1. If I were you then I would get a 9800 GTX, that way tri-SLI will be a possibility.
August 5, 2008 7:34:05 PM

Made the choice...

we're getting two 9800GTX+ cards... and then we'll move to SLI later for our computers.

We don't have any plans to move to Tri-SLI anytime soon... maybe in generatioin beyond the nVidia 280 cards?... and then maybe not.

The only thing we're not sure of is if we'll need new PSUs when we make the move to SLI again... but that's probably a couple months away.

Antec PSU's are great. And an Antec 650W should be plenty to run twin 88/9800 cards.

Don't put to much stock into the "Overclocked" video cards. They usually don't give you THAT much of a performance boost, as some of them really aren't even OC'd by very much. And if you really want to OC it, you can do it yourself and save money.
August 5, 2008 7:49:18 PM

The 9800GT is just a 8800GT with a different sticker on the box.
Nvidia wanted to fully retire the GF8 line and still keep selling the defective G92 chips.
Hence, keep the same product and rename it.

For the rest of you questions...

SLI 7950GT's should perform just a little below a 8800GT/9800GT (which perform 100% the same barring any driver weirdness) in older games that scale good with SLI. In newer games, a *800GT will take the lead.

Yes, a single 8800GT/9800GT will beat SLIed 8600GT's.
A 8600GT is similar in performance to a 7600GT.
Your 8600GT SLI performs worse that the older 7950GT SLI.

Two *800GT cards will perform at and above the level of the GTX 280 for much less.
They should run on your current PSU.

The 9800GTX+ will beat a single *800GT bye a decent margin.
It uses a fully functioning G92b GPU with it's full 128 stream processes compared to 112 on the *800GT and runs faster to boot.

Another card to look at would be the 4870.
You can get it for as low as $255 on newegg.
It will perform much faster than a single 9800GT/GTX and almost as fast as *800GT SLI.
It will also avoid any potential problems with SLI scaling.

the 8800 gt is a 65 nm version and the 9800 gt is a 55 nm version with 9 series architectural improvements... so there is a difference
August 5, 2008 7:56:23 PM

are you limited to nvidia cards?
August 5, 2008 8:01:19 PM

We considered the ATI card, but our mobos support SLI and not crossfire, we like our mobos and don't want to upgrade those this soon... but we feel it's time to upgrade our graphics cards for now.

The only reason I was thinking of needing new PSUs was that the 9800GTX+ cards use dual PCI-e power connections... and our PSUs only have 2 of those... so if we run SLI we'll need FOUR 6-pin PCI-e power connections... yikes... but if the 650w PSU has enough juice, we could just get some adapters to turn 2 plugs into one PCI-e power plug I guess.

.... to be honest though, I'm not sure I have 4 regular plugs free that I could turn into two more PCI-e power plugs. lol.
August 5, 2008 8:05:27 PM

8800GT = G92 with 112SP 600/1500/900
9800GT = G92(b) with 112SP 600/1500/900

Some of the 9800GT's will be based off of the shrunken G92b which will give them slightly lower power draw and better potential for overclocking.
Some are still based off the older 65nm G92.
They bouth have the same feature set and only support 2 way SLI.

From here they look the same.
August 5, 2008 8:05:58 PM

I think just because our motherboards support SLI is the only real reason we'd like to stick with nVidia. To be honest, I've always been more of an ATI guy... but when nVidia started blowing ATI away with Price vs performance... I crossed over to nVidia. I think the AMD buyout and such had a bit to do with things... but it seems ATI is starting to get back into the swing of things.

ATI has a chance to get me back in a year or so when I'm on the market for new mobos again.

That's a very neat idea, actually :) 

Here are some benchmarks: HD 4870 is about the same as the 9800GX2 (which in turn is very much like 8800GT SLI):
http://www.neoseeker.com/Articles/Hardware/Reviews/diamondhd4870/11.html

With the HD 4870 you only need 2 6-pin connectors, so I guess it solves that problem too.
August 5, 2008 8:23:00 PM

HD4870 seems to be a bit higher than we want to spend. I'm seeing prices at 255 after $30 rebate.

I'm looking at $199 for the 9800GTX+.... also, the BFG Tech OC'd version is only $199 as well.

I've delt with both XFX and EVGA tech support, RMA and exchanges and both were just fine.... never owned a BFG card though.


Also, don't I lose PhysiX support if I go with ATI??
August 5, 2008 8:29:29 PM

No, PhysiX can be done on the CPU also.

The problem with doing it through the GPU is the GPU already has it's hands full working on the graphics. There are not so many games that support PhysiX in any meaningful way anyways. The current trend is more towards the fully open source Havoc physics engine.

Yes, the 4870 will cost a bit more but it will more than make up for the cost increase bye way of it's performance gains.
August 5, 2008 8:30:50 PM

There's a bit of story as to why I have such funny 7950 vs 8600 current setup. I'll make it super short...

bought two 7600GS cards (one for each PC)... then found a deal on a forum for two 7900GT cards. When the 7900GT cards arrived I put the 7600 into my wife's PC... but the 7900GT cards had a BIOS issue with 680i chipsets. Even a BIOS upgraded failed to make it work... so EVGA upgraded both my cards to 7950GT cards, nice.

....then one of my wife's 7600GS cards died... XFX then did an RMA, and unknown to me... gave us a free upgrade to a 8600GS... BUT, this of course broke her SLI setup... so after some talking to XFX, they allowed us to RMA the other 7600GS card and they then sent us another 8600GS card.

lol.

Originally the idea was for us both to have the same setup.... but due the graphics card issues and deals we ended up where we are now. So getting the new graphics cards is our way of fixing our current issues.

... but that doesn't include the motherboard fiasco we've also gone through, lo.
August 5, 2008 8:31:05 PM

ATI does not support PhysX.
As long as you want SLI, don't even consider ATI.
a b Î Nvidia
August 5, 2008 8:32:56 PM

With ATI, you lose PhysX and gain Havok. For example I'm a big fan of Diablo and Diablo 3 will support Havok, so I'll get myself an ATI card when the game is out to replace my 8800GTX.

You're looking at $199 now, then some time with lower performance, then another $199 later. The ATI alternative is $285 now, the whole performance up-front, and a $30 rebate check later. You'll end up paying more with the SLI approach.

August 5, 2008 8:33:30 PM

So... as of right now...

a single 4870 will out perform an SLI 9800GTX+ setup in all games? My resolution is only 1680x1050 native for my display and that won't get upgraded for a while.

Does my motherboard have to support crossfire to add another card later though??

LOL. SLI is not the target here, it's just one possible path to it. If the target is maximum performance under $400, 9800GT SLI and HD 4870 are two possible paths, both with about the same result, but the SLI path costs $145 more.




August 5, 2008 8:38:46 PM

I could care less if I have SLI... I just want more performance for my $$$. As far as I've read there's no real big advantage of either SLI or Crossfire.

Basically, the ony reason I have SLI now is because I got a good deal on some 7900GT cards (if you read my earlier story).

On the flip side though... I assume if I ever want to add another graphics card I'll have to change to a Crossfire motherboard.

Is ATI having any driver issues? When I was an ATI guy I had endless issues in my games due to driver support... what I can say now is that I've not had these issues with my nVidia setup... but I've not looked at ATI since my old 9800pro AGP card.

Not just that, but keep in mind the GF7 series just does plain awful in some of the newer games. Even if we say 80% scaling for the SLI 7950GT setup, in titles like UT3 the single 8800GT would still be ahead. http://www.anandtech.com/video/showdoc.aspx?i=3128&p=4


OP: forgive me if it's been mentioned(didn't read the whole thread), but two 9800GTX (one per machine) would be a nice option for you. Then later SLI them in one machine if you like.

A single HD 4870 will outperform SLI 9800GTX+ in some games (World in Conflict, Call of Juarez, etc.). It will lose against the SLI in others (Crysis).
In most games it will be tied. That is, both the single HD 4870 and the 9800GTX+ SLI can get over 60 fps, which is the most your monitor can display (assuming 60Hz refresh rate), so it doesn't matter which video card can produce more fps. If a setup gets 150 fps and another gets 90 fps, then that's a tie, for all sane purposes.

Yes, you'd need an x38 or x48 or at least a P45 motherboard to combine two HD 4870 cards in Crossfire.



August 5, 2008 8:44:49 PM

... so although I see the point of the ATI way being cheaper... don't forget to add in that I'll need a new motherboard to do crossfire... that's like another $150-$250 right there... plus the cost of another 4870.

So I guess it's this...

cost of two 9800GTX+ cards (plus possible cost of new PSU)
vs
cost of one 4870 (plus possible cost of new PSU) ((then if I get another 4870, the cost of that plus another motherboard))

The biggest difference I see right now is that as someone said... the 4870 has the performance right now at a cost of $80 more... vs spreading out the performance and cost going the SLI way.

...but if the 4870 kills two 9800GTX+ cards in SLI maybe I should get that one?

You guys aren't making this any easier, LOL.
August 5, 2008 8:48:45 PM

The idea was since I have three SLI ready motherboards...

buy two 9800GTX+ cards now... we both get one... then the 8600GS setup can go to my HTPC in SLI mode... then in a couple of months... buy two more 9800GTX+ cards and enable SLI in both mine and my wife's PC.

But... it's hard to say no to the 4870 if it can kill two 9800GTX+ cards in SLI.
August 5, 2008 8:55:29 PM

Let me try to make this easier...

I'm running an 22" LCD monitor with 1680x1050 res at 60hz... I usually enable vsync in my games so that I don't get tearing of the image.

I play games like C&C3, Red Alert 3 (beta), Supreme Commander, UT3, FEAR, Orange Box, etc.

I also like to have ALL the eye-candy turned on and as maxed as possible, but still get a min of 60fps.

I'd also like to enjoy Crysis maxed out.

Again, $$$ is a big factor here... as we'd rather not spend over $200 per card.... BUT of course we are for sure considering the 4870 since in our current setup it might beat the 9800GTX+ SLI setup.

I just comes down to which will perform better in most games with my setup (going for the 60fps with everything maxed)... the 4870 or the 9800GTX+ SLI configuration?

Hmm, I see what your saying, and agree in part, but 8800GT SLI typically beats an HD4870 by a clear margin, so SLI 9800GTX+ is obviously a more powerful solution. Whether or not it's needed in a particular game is another story like you mention. SLI scales well in COD4 for example, but a single HD4870 still does amazing at 19x12 4x/16x. Not the same for all games though, even aging Oblivion's outdoor foliage will put a hurting on the HD4870 so we are no longer talking 90 vs 150 fps in quite a few games. SLI scales awesome in that game area, but I can still reduce my pair of 8800GT to 30 fps in the lushest foliage at 19x12 4x/16x max. And as more crysis like games come out, 9800GTX+ SLI's playable advantages may appear at sane resolutions even. How will Fallout3, Farcry2, etc. be?

In this review - 5 out of 7 games 8800GT SLI beats the HD4870 (raw fps wise) - http://www.anandtech.com/video/showdoc.aspx?i=3341&p=13
August 5, 2008 9:26:55 PM

Here is something for you to chew on.
Remember that the magic number is 60FPS to match your display.
All results are with early 4870 drivers and from the Anandtech review.
All from the 1680x1050 tests...

Quote:
Crysis:

46.1 8800GT SLI
51.0 9800GTX+ SLI
35.6 4870 single

COD 4:

119.8 8800GT SLI
112.9 9800GTX+ SLI
98.9 4870 single

ET: Quake Wars:

109.4 8800GT SLI
146.3 9800GTX+ SLI
111.2 4870 single

Assassin's Creed:

63.6 8800GT SLI
61.9 9800GTX+ SLI
57.1 4870 single

Oblivion:

66.9 8800GT SLI
78.6 9800GTX+ SLI
48.5 4870 single

The Witcher:

62.4 8800GT SLI
67.5 9800GTX+ SLI
58.7 4870 single

Bioshock:

123.8 8800GT SLI
112.6 9800GTX+ SLI
118.9 4870 single


Again, this is with very early drivers.
With newer drivers, performance of the 4870 series is sure to raise but you can never be sure bye how much.
All but two of these games keep the 4870 very near or above the magic 60FPS barrior.
You can see that 8800GT SLI will stay above 60FPS in all but one game, though.

As for cost...
8800GT SLI will run $280 before MIR's, $240 after.
9800GTX+ SLI will run you $400.
A 4870 will run you $285 before MIR and $255 after.

Just from the price performance ratio, 8800GT SLI would be your best bet.

A few things to keep in mind, though.
SLI dose not scale with every game, it requires driver optimisations to give top performance.
As such, when you have the choice between a 2 card setup and a single card setup with similar price and performance, you should always chose the single card setup. This will avoid any potential problems with scaling. However, this is not totally the case as SLI 8800GT's has the potential to put a hurting on a single 4870, but they are fairly close in many games.

Like I said, just a few things to chew over while you make your decision...
August 5, 2008 9:54:49 PM

That anandtech review helped a ton!!

I just got done running through the numbers myself...

We're going the 9800GTX+ route... not only do we plan on doing SLI, but we can spred the cost out over a few months and in the long run it will be cheaper. That plus the fact that when I looked at crossfired 4870s in that review, they were mostly below the SLI of 9800GTX+ cards. A few spots ATI won, but not enough in my eyes to make me go the extra cost. Also, the 9800GTX+ setups used less power than the 4870!! Giving me a better chance at not needing another PSU.

The final cost if I run SLI 9800GTX+ vs CrossFire 4870
9800GTX+ SLI Config
$200 per card x4 = $800
total = $800

4870 Crossfire Config
$255 per card x4 = 1020 (after rebates)
avg $200 x2 (no mobos) = 400
total = 1420 w/new mobos

Both have about the same need for me to get new PSUs so that's a wash... but the fact that the 9800GTX+ uses less power gives me a better shot at not needing to buy new PSUs.

Overall the 9800GTX+ setup performed better as well... I know SLI is needed in some cases.. but again, the final cost is still cheaper as I didn't see all that big of a boost from the CF setups.

August 5, 2008 10:10:59 PM

One thing you are off on is the requirement of a new motherboard.

Any PCIe GPU will work in your current motherboards.
What will not work on a nVidia motherboard is CrossFire (AMD's equivlent to SLI).

As such, you will not need to purchase new motherboards to run single 4870's.

If you do decide to purchase new Intel motherboards, which would not be a bad thing as nVidia Mb's are not the best, I would recommend 2x 4850's in CrossFire.
That setup WILL beat a SLI 9800GTX+ setup, especially with the newer drivers.
The down side is that you will be stuck paying and extra $1600-$290 per system (over SLIed 9800GTX+) depending on the motherboard.

So really, you will either be spending $510 for 4870's or $960-$1090 for 4x 4850's and 2 new Intel motherboards.
This would be compared to $480 for 2x SLIed 8800GT's or $800 for 2x SLIed 9800GTX+.
August 5, 2008 10:27:54 PM

I know I don't need to buy a new motherboard to use a single 4870... but overall the SLI config of 9800GTX+ still beats the CF cofig of 4870 so the ponit is mute as not only will I get overall better performance... it's gonig to be cheaper for me in the long run to stick with SLI vs swapping my motherboards to get the CF boost.

EDIT...

sorry, missed the 2nd part of your post...

I guess I'm not sure were you getting the idea that a sigle 4850 or 4870 is better than two 9800GTX+ cards in SLI. It seemed obvious to me in the anandtech review that 9800GTX+ SLI config beat both the 4850 and 4870 hands down in like 95% of the tests. Or am I missing something???
August 5, 2008 10:30:02 PM

Quite true.
With the hardware you have now, your best price performance pick would be with the nVidia camp.
Just wanted to make sure you knew that you could use a single ATI card with your current hardware to.
August 5, 2008 10:38:48 PM

no problem... I think it was how I worded my "cost vs cost" post.. I added the "CF vs SLI" thing. ;) 

Still... I edited my previous post and am wondering why you say this:
"I would recommend 2x 4850's in CrossFire.
That setup WILL beat a SLI 9800GTX+ setup, especially with the newer drivers."

that's not the impression I got when I compared the CF 4870 setup and the SLI 9800GTX+ setup on the anandtech review.

but again, I've been known to miss things so please explain your thoughts. :)

Paul, what do you think about this 9800GX2 at $284?

Wow, Nice find! I've never seen one that cheap. I'm not crazy about the sandwich design, but I think that's an awesome setup for the price (I want one on a P35 mobo). Man, the HD48x0's are just awesome, both in performance and what they have done for pricing in general.

two 4870 in Crossfire vs two 9800GTX+ in SLI at 1680x1050

Crysis
4870 CF = 39
9800GTX+ SLI = 51 (wins)

CoD4
4870 CF = 171.4 (wins)
9800GTX+ SLI = 112.9

Quake Wars
4870 CF = 109
9800GTX+ SLI = 146.3 (wins)

Assassin's Creed
4870 CF = 54.5
9800GTX+ SLI = 61.9 (wins)

Oblivion
4870 CF = 79.4 (wins)
9800GTX+ SLI = 78.6

The Witcher
4870 CF = 71.3 (wins)
9800GTX+ SLI = 67.5

Bioshock
4870 CF = 129.8 (wins)
9800GTX+ SLI = 112.6

Power Consumption
4870 single = 203.7watts
4870 CF = 273.1watts
9800GTX+ single = 187.9watts (wins)
9800GTX+ SLI = 250watts (wins)



It's about a 50/50 split on the games... and I'd personally call the "Oblivion" and "The Witcher" tests a wash as they're pretty close.

Here is something for you to chew on.
Remember that the magic number is 60FPS to match your display.
All results are with early 4870 drivers and from the Anandtech review.
All from the 1680x1050 tests...

Quote:
Crysis:

46.1 8800GT SLI
51.0 9800GTX+ SLI
35.6 4870 single

COD 4:

119.8 8800GT SLI
112.9 9800GTX+ SLI
98.9 4870 single

ET: Quake Wars:

109.4 8800GT SLI
146.3 9800GTX+ SLI
111.2 4870 single

Assassin's Creed:

63.6 8800GT SLI
61.9 9800GTX+ SLI
57.1 4870 single

Oblivion:

66.9 8800GT SLI
78.6 9800GTX+ SLI
48.5 4870 single

The Witcher:

62.4 8800GT SLI
67.5 9800GTX+ SLI
58.7 4870 single

Bioshock:

123.8 8800GT SLI
112.6 9800GTX+ SLI
118.9 4870 single


Again, this is with very early drivers.
With newer drivers, performance of the 4870 series is sure to raise but you can never be sure bye how much.
All but two of these games keep the 4870 very near or above the magic 60FPS barrior.
You can see that 8800GT SLI will stay above 60FPS in all but one game, though.

...

Keep in mind, those are average FPS not minimum fps. A 57 ave is not staying near or above 60 fps (if that's the goal). Also, they are quite likely ( at least often) timedemos not actual gameplay. 40 fps in the Crysis GPU bench could drop to the 20's in actual gameplay in demanding levels. Anyway, not knocking the card one bit though... I would still be more than thrilled gaming at 16x10 (or even 19x12) on an HD4870.

good points. I'm sure I'd be happy with either card or sets of cards running in my PC, lol.

Next big question...

should I get the XFX or EVGA version of the 9800GTX+ on newegg? I say EVGA, the wife says XFX, LOL!
August 5, 2008 11:34:19 PM

Quite true and I probably should have worded that a little better to show that.

@teknomedic,

It is way past my bed time so I am not going to dig for any benchmarks but I will leave a few words for you tonight.
This Anandtech review was done very quickly at release with very early drivers, V8.5 if I am not mistaken.
The 48x0 cards were not officially supported until the 8.7 driver release.
In the time between the Anandtech review and now, many issues have been fixed with the 48x0 series cards.
One that I have seen is that they now scale near 100% in ET: Quake Wars.
I have seen improved scaling in other games but I can not remember the details at current.
A little time searching on google should give you some more benches.

My statement that 4850Cf would beat 9800GTX+ SLI is based on a few facts.
When placed 1 on 1, the 4850 will match to outperform bye ~15% the 9800GTX+ in most games.
Crysis is the noticeable exception to this and although ATI clames to be working on this issue, only time will tell.
Once ATI drivers have been properly written, CrossFire has shown the potential for near 100% scaling in many games.
With this in mind, once proper drivers are out for the 4850, it should be able to match or exceed 9800GTX+ SLI.

Of course this will make no difference for your needs.
The lower cost of 2x 4850's compared to 2x 9800GTX+ is more than offset buy the price of a new motherboard and the performance benefit is not enough to cover the price gap.
Just a quick rant to show the reasoning behind my previous statement.
With your current hardware it makes much more sense to stay with nVidia.

Now, I gotta sleep.
The damn alarm starts going off in another 5.5 hours :cry:

thanks for the reply... go to bed, lol.

I understand where you're coming from now and it does seem that if I was building a fully new PC then I should take a good look at a crossfire setup... and to be honest I probably will... but my time for new PC probably won't come until the generation after the nVidia 280.

So long thread short...
9800GTX+ for me... but others should consider 4870.

Also, I think I'll go with the XFX 9800GTX+ since they offer a warranty that can be transfered to a new buyer when I sell the card later... pretty neat. ;)
