hey guys im just trying to find the best bang fr the buck and i noticed 8800 gt is only 110 free shipping at newegg... so i was wondering if it is possible to tri sli them?

More about : tri sli 8800

September 13, 2008 5:28:55 AM

no, the only way you can tri sli would be to get the 9800 GT which is bascially a 55 nm, tri sli enabled 8800 GT, one of Nvidia's renamed cards:) 

September 13, 2008 5:29:59 AM

will it be the same as the 8800 gt?
how much performance would that give?

no, it isn't possible. They do perform decently in sli, though (especially for the price).
September 13, 2008 5:34:17 AM

so is it possible or not?
is this card good with aa and af enabled when in sli or tri sli?
September 13, 2008 5:39:33 AM

The 8800 GT is slightly (mean slightly, 0-5 fps) slower than the 9800 GT.

The 8800 GT supports sli, BUT not tri sli.

The 9800 GT supports sli and tri-sli.

2 8800 GTs in sli come close to matching 1 9800 GX2.
September 13, 2008 5:42:56 AM

wow those are some serius benchmarks for $220, thats much more than a 4850 at almost the same price, why isnt the 8800 gt the best bang for the buck? it is jst $110...
September 13, 2008 5:49:28 AM

A 4850 is around $160 after rebate.
2 8800 GTs are $220 after rebate.

They are around the same price/performance value. Remember, if you are doing 8800 GT SLI you need an Nvidia motherboard, which tend to suck.
September 13, 2008 6:09:17 AM

SLi performance comes at a hefty price. Youll have to deal with horrible Nvidia chipsets.
September 13, 2008 6:17:17 AM

and according to benchmarks 2 8800 gt are way more than 1 4850. And they are $220 before rebate...
September 13, 2008 6:56:00 AM

Neither the 9800 GT nor the 8800 GT can do tri-SLI. The cheapest card that can is the 9800 GTX.

no ur wrong the 9800 gt can

Not all 9800gt can do tri-sli. If you look at the cards you'll see than only ONE of the ASUS cards can do it.
September 13, 2008 7:38:47 AM

so whats the diference of a regular 9800 gt against a 8800 gt?
September 13, 2008 7:48:27 AM

triple sli vs normal sli does not scale very well in most games... i wouldn't bother. it's certainly physically impossible to sli-bridge three cards, but you could run them without a bridge like that university running four 9800GX2's on a CF board (obviously without bridges). this didn't matter to them as the cards did not communicate with each other, they individually communicated with the cou. if your cpu was fast enough and you made your own drivers or modded existing drivers...? you never know...
September 13, 2008 8:26:43 AM

oh thats nice to know... so i think ill stick with 2 8800 gt ...
thatll give me enough performance to run anything maxed right?
crysis at very high directx10?
all this at 1680 x 1050...

You might think so but it's not going to happen. You'll find you need to turn back settings until you find a level at which to play the game. You might get away with most settings on high though...... no AA

Try it at 12x10.

No it is NOT impossible. http://hothardware.com/Articles/NVIDIA_3Way_SLI_Performance_Preview/ look closely at the bridge being used.
September 13, 2008 9:37:19 AM

The resolution is a bit annoying, coz otherwise im sur eit would easily do crysis at very high. Actually i think you could. I have a 8800GT OC (700MHZ) Which can just about hanle very high (20+ FPS) on a widescreen 1440x900. I think adding in another OC in sli would handle it nicely. Maybe even some AA i dont know. Shame as i dont have an sli board
September 13, 2008 12:20:25 PM

The 9800 gt does not support triple SLi the 88xx GTX and the 98xx GTX as well as the 280 do.

Don't talk out of ur @ss please read about the card, the 9800 GT is basically a revision of the 8800 GT wit 55 nm processor and tri-sli Support.

Read reviews ppl:) 

And yes I think triple sli is going to benefit i the future, since games are becoming more and more optmized for multi core gaming.

My quad scales in almost every game. Tri-sli and quad are becoming more mainstream by each coming day, just like regular sli wasn't used at all before, now you can find it in most systems and even laptops.

Actually all 9800GT's right now are still 65nm, everything else you've said is spot on. I read that they are supposed to transition to the 55nm by October but won't bet on that. Some are supposed to be 55nm now but that could just be rumor. To the OP if you want to go with the 9800 GT try the Asus one at the egg.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Its basically a 9800GTX that uses less power as far as I can tell.

I posted this above............. but you selected the WRONG asus card...... it's the other one.......... and it's the only one that supports tri-sli........... look at the side view pictures. You should be able to see the connectors.

I kno that 8800 GT don't come in 55 nm, I said that the 9800 GT is Just a renamed 8800 GT with a 55nm proccesor.

I never stated that the 8800 GT has a 55 nm processor. The 9800 GT still holds less Stream proccesors than a 9800 GTX...and not only that but it is 75 Mhz slower. So it is Still under the 9800 GTX and even the 8800 GTS 512.

9800 GT = 112 Stream processors Clocks (600, 1500) 55nm
8800 GT = 112 Stream Processors Clocks (600, 1500) 65nm

So actually its like a 8800 GT that uses less power not a 9800 GTX:)  They perform the same.

9800 GTX = 128 Stream processors Clocks (675, 1688) 65nm
8800 GTS = 128 Stream processors Clocks (650, 1625) 65nm
9800 GTX+=128 Stream processors Clocks (738, 1836) 55nm

actually i believe it does run everything maxed, check this benchmarks
dagger posted... its a tiny bit inferior to the 9800 gx2 (8800gt sli)...

September 13, 2008 4:07:42 PM

does anyone have 8800gt in sli so u can tell me if those benchmarks are true...?
September 13, 2008 4:12:34 PM

yes they are, the 8800 GT in sli beats 1 280 GTX. It has alot of power underthe hood, it consumes little wattage, and its not dual slot which means it doesn't take up alot of space. You could get dual slot so that its cooler, but I doubt the GTs heat that much.

You should Ask TGGA he has an 8800 GT sli Setup and he can back up the above facts and my own.

Its him you should talk to if you want it straight from the gorilla's mouth:p  :D 
September 13, 2008 4:19:24 PM

thanks liquid, if those cards were indeed better than a 280 then it does run anything maxed im i right?
September 13, 2008 4:26:21 PM

anyhting current gen yes it also depend son your resolution don't expect much for Crysis 1 but Crysis 2 you should be more than fine.

AA and AF might pose a problem further down the road though.

Seach google 8800 GT sli, and you should get alot of results.
September 13, 2008 4:51:33 PM

well, it showed 46 fps on my resolution so that cant be too bad i hope thats at very high...
also whats wrong with aa and af?
is this card bad with AA and AF?
September 13, 2008 4:55:24 PM

i game on a small resolution... 1680 x 1050

Not as good with AA and AF as 4000s ATI cards, better than 3000s. It handles them decently.

http://www.anandtech.com/video/showdoc.aspx?i=3341&p=13
This benchmark is done with shaders at Very High, all other settings High. Shader setting is the most intensive one, and affect both performance and visual the most. Of course, if everything else is set to Very High, it'll drop below 46.1 fps.
September 13, 2008 5:03:41 PM

oh.... how long do u think they would last handling games at max details before they get obsolete and i have to change them, because i could also go for 9800gtx+ in sli... and they are tri sli comptatible...
how do those handle aa and af?

Crysis is not the normal game. You should be good for quite a while.

9800gtx+ sli will outperform single 9800gx2 due to faster core clock, and certainly outperform dual 8800gt. Although they cost much more than 8800gt.
September 13, 2008 5:21:54 PM

i can get for $360 after shipping...
they are overcloked to 725 core clock memory clock at 2320...
they should do austanding in sli and they are tri sli capable right?

The 9800gtx is tri sli capable, so I believe 9800gtx+ is too.

Not sure if they outperform 9800gx2 by enough of a margin to justify the $360-280 price difference. It cost 29% more, but is unlikely to perform 29% better.

Especially since the $280 9800gx2 model is factory overclocked from 600mhz stock to 675, a 12.5% increase.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Tri sli the 9800gtx+($360x1.5) costs $540. Quad sli the 9800gx2 ($280x2) cost $560.
September 13, 2008 5:39:19 PM

also is a 850 Watts psu enough for 3 9800 gtx?
September 13, 2008 5:42:25 PM

yes but i think 3 9800gtx will scale better than quad sli with the 9800gx2...

Nica Guy said:

It should be enough. Although you might want to go higher just to be safe.
http://www.anandtech.com/video/showdoc.aspx?i=3341&p=22
Note that 9800gtx+ isn't very efficient, merely 25 watts lower than 9800gx2 at full load, despite the smaller 55nm process, because as clock increases, power efficiency decrease at an growing rate.

There aren't any 9800gtx+ tri sli benchmarks, but since it only slightly outperform 9800gtx, you can get an idea on performance by looking at 9800gtx tri sli benchmarks.

also i just noticed the 9800gtx comes with a game and with 2 of them i have 2 games i can sell for $20 each... so it just went down to $320 for 2 9800gtx+.

Games tend to be hard to sell. People are fickle, and will assume you swiped the cd key. :D 

Also keep in mind mail in rebates are limited one per customer.

ill sell it to a friend :) 
September 13, 2008 6:35:05 PM

also, how well does aa and af work with 9800gx2?
wil i be able to run any game maxed at 1680 x 1050?
also how good does it work in quad sli?

The tri sli benchmark do include 4x AA in Call of Duty 4, and 16xAF in all benches.
http://www.hardocp.com/article.html?art=MTQ5Niw2LCxoZW5...

Not sure how it would scale. But both cards use gpus with identical architecture, so whatever it is, they should scale around the same.

Yes, tri-sli and quad sli will definitely be able to handle max settings at 1680x1050.
September 13, 2008 6:41:08 PM

They run alright, but better on an amd card. Yes, with a 9800gx2 you'll be able to max most games out. Right now, the driver support isn't very good, so it scales pretty bad in quad-sli.

9800gx2 scales very well in quad, considering it's quad. It's old, and drivers are already mature.

See fps chart for CoD4, at some resolutions, it nearly doubles fps over single 9800gx2, an almost 100% scaling!
http://www.guru3d.com/category/vga_2/
Of course, most other games scale far below this level, but still rather decent. You have to look at up to date benchmarks, not old ones on beta drivers.

4870x2 quad cf scales badly right now due to new drivers. Give it equal amount of time that 9800gx2 had, and it should scale just as well.
