8800GT SLi < or > single HD4850? :bounce:  the one component left for me to choose!

More about : 8800gt sli 4850

Depends on the games you're playing. A lot of games don't scale well with multiple GPU setups, so SLI won't be doing you any favors.

You'd do better by futureproofing and going with the 4870. However, since that's not a choice, go 4850. DirectX 10b support dontcha know.

SLI 8800GT will PWN a single 4850.

well yes, i know that new ati chips have dx10.1 on then but big deal! by the time games that need it are coming out, there will be dx11 chips! also, the 4850 is too high priced, and 2 8800GT's are extremely close to a single 4850 if ya shop around a bit...
July 29, 2008 7:59:56 AM

the idea of GDDR5 really appeals to me, but unless 4870's drop to less than $250 its a no go...
July 29, 2008 8:04:20 AM

also, im looking at an evga 750i FTW if im goin nvidia sli, or a P45 if i choose a 4850... im a bit worried about cpu cooler clearance on the P45's where the 750i has a specially sloped NB HS especially for this purpose....i also like the idea of EPP RAM modules, simple OCing of a Q6600 (i saw a review with a 10 second OC to 3.6 WOW!) also my inner nerd screams for 2 graphics cards LOL... only con for the 750i is the HOT NB (even with the bundled NB fan, which is uber loud :(  ) so...

If you are looking at an entire platform, the P45 would be my choice.

While SLIed 8800GT's offers a hell of a bang for the buck, nVidia's platforms are fairly junky.
A P45 based Mb with a single 4850 (which are going for $170 or less after MIR, not that much more than a 8800GT) would be better for a few reasons.

First, a decent P45 Mb will be a more stable and better overclocking platform than any 750i based motherboard. If you are planning on overclocking a Q6600, you stand a much better chance of reaching 3.6Ghz on an Intel Mb as compared to a nVidia Mb.

Second, for games that do not scale with multi GPU's, a single 4850 will far outperform a single 8800GT.

And finely, when you have a few extra $$, you can CrossFire your 4850 for a system that is more powerful again than SLIed 8800GT's.

As a side note, just because some Q6600's are capable of running at 3.6Ghz don't plan on yours running that fast. With out a high end system and extensive cooling, most Q6600's are only overclocking to 3.2-3.4Ghz. Even then, you will have more than enough power.
July 29, 2008 9:04:28 AM

yeah yeah im only aiming for 3.0GHz without a voltage change... :bounce:  so i think it should be k on the whole CPU overclocking side... EPP certified RAM shouldnt be a problem like other RAM's which ppl are going psycho about... and 8800GT's run cooler, and i can easily use the evga precision overclocking tool to increase fan speeds, core, shader and memory clocks in sync or out of sync! DIE RIVATUNER DIE!!
July 29, 2008 9:53:22 AM

2 8800gt at newegg are 140 each so that is 280 and for this you can get a 4870 and blow the 8800gt away.. And a 4850 is is around 155 after MIR. tell me where you can get 2 8800gt for price of a 4850????
July 29, 2008 10:08:17 AM

currently a single evga dual slot 8800GT is $120 (dual slot=much cooler and uber kewl overclocking!!!!!!) and a single 4850 is maybe 10 or 20 bucks below that price...is it worth it?
July 29, 2008 10:14:00 AM

even overclocked the 8800gt is slower that 4850.. it really depends on what you want. i always get the best card for the money. cost vs performance. i have nver had a lot of luck overclocking any video card and gettting a lot of improvement out of it. unlike with cpu's.. I have my q6600 at 3.6 at 1.48v on a rampage formula. So i know you will enjoy the CPU. I could get 3.2 and not c hange any voltage on it. Look at all the reviews on this site, xbitlabs and anandtech and you can see how the cards perform.. one site compares the 4850 and the 4870 to SLI cards and Crossfired 3800 cards. good luck and have fun with your PC

lol but im using TWO 8800GT's :D

Isnt that the same guy who was complaining about many problems that he claims for the HD 48xx and says that a single 8800gt will outperform a single H 4850 loool

Golden rule of thumb for buying video cards:
BUY THE SINGLE BEST CARD YOU CAN AFFORD

Then later when the "juice" seems to be going out of it, and the price has dropped on your card, buy another and crossfire or sli.

Do not buy upfront 2 lessor cards planning on Crossfire or SLI to make up the difference of a higher tiered card.

I don't feel that Golden rule is a good rule anymore. I did ages ago and for lower end cards that don't add up to a single high end in performance. And, of course, If we are talking about the same price and same performance, I totally agree go with one card.

But price/performance has shifted to greatly favor multi GPU. This was even more true before the HD4870 release. But still, SLI 8800GT will more often than not easily beat an HD4870 and even trades blows with the GTX 280. Plus, adding a second card later often doesn't work out too well as prices/availability vs new gen cards. I think the very best time to consider SLI/Crossfire is grabbing the best performance for the price right off the bat, not hoping to add a card later on. (unless it's a short time frame)

Anyway, if going with an SLI mobo, why not consider SLI 8800GT or GTS 512MB, etc. for $250-300. But, at least the HD4870 now finally gives an excellent (high end) GPU solution to go with an Intel chipest, or two HD4850 and an Intel crossfire compat. mobo.

But I should add, two 8800GT or one HD4850 is not an equal comparison. The HD4850 is priced so well it's a great buy, but we are not talking he same performance. Two 8800GS would be similar prices. Two 8800GT or one HD4870 for $250+ is a question I'd more expect to see.
July 29, 2008 4:34:09 PM

If you had the budget to run to 4850's in Cross, then i would without a doubt run two of those. Asking if one 4850 will out perform 2 8800Gt's in SLI, Thats just a dumb question
July 30, 2008 3:54:13 AM

I'm facing a decision similar to the original poster, and I have a couple of concerns that are relevant I think:

1) The 4850's originally had heat issues -- they idled at like 70 degrees F or something I believe. Have they solved those issues on most pf the 4850 cards, or do people just use after-market cooling solutions to keep the temps in check?

2) The nvidia chipsets still have issues with hard drive / i/o performance, I believe -- so this might also impact the decision of MB. Wouldn't the p45 give better hard drive performance compared with the nvidia?
July 30, 2008 4:39:06 AM

It will, but don't buy two high end cards to run on that chipset. You will not get the full performance of two 4850's on a p45 chipset like you will on a x38 or x48 chipset. Just to let you know.
July 30, 2008 5:45:04 AM

ok, let me clear a few things up.... im looking at 2 8800GT's (NOT GTS, NOT 8800GS....) or a SINGLE 4850, not crossfire... also, lets just say that hte prices are pretty much the same for the sli 8800GT's and single 4850....im looking at performance here just trust me about the prices.

also, im not running some RAID array or anything so all i care about is if a single HDD works fine on the GROUND BUILT 750i FTW.... its not a reference design by any means.

why is it every stupid post comment i see is from concrum??

do you actually ever check your facts before you make such stupid comments , several sites have benchmarked this combination and the ati cards win every time , im sure you work for nvidia or possibly ati have banned you from owning there cards because you probably emailed them with your wisdom!

Mate, seriously, ask any of the regular forum posters on here, by the time your single card isnt up to the task, you could get a better single card that would cost you less than it would buying another original card.

all im interested in, is the performance comparison between the two configurations. when either one is out of date, there will be faster CPU's, faster RAM etc and i will need to get a whole new system! in which case i would just get a whole new high end single card or dual mid end. only way you get sli is in the now. read around bro :pfff:

Where are you getting 8800 GTs for $75-$80 each?

Peace of cake: performance based 8800GT SLI is far better. It will be the rare exception game that the the SLI combo loses. If for whatever reason, it's priced the same..... IMO it's an easy decision.

Have a look for yourself here's a whoopin' in 7 of 7 games.

And so you know, 8x/8x sli on 750i will not kill your performance on those 8800GT's. Here you can see 750i GF8800 SLI matches 780i SLI:

I figured for him the HD4850 is rare and $$$.
July 30, 2008 3:36:48 PM

I thought the performance issues for the nvidia chipsets was for *both* a 2-drive RAID array and for the basic i/o performance from a single drive? Just that the 2-drive RAID array takes a much bigger hit compared with the intel chipsets?

Is that correct?

If that is right, that's why -- for me -- I decided on the P45 and the 4850, because I also want good i/o performance from my single drive.
July 30, 2008 4:12:09 PM

Or alternatively, they could already have a single 8800GT, or have an older card that they can step up to the first 8800GT; if they could get like $100US back for whatever card they had, then they'd only wind up spending a comparable amount to the 4850 to get both 8800GTs.

But yeah, if you're going on power, then take the 8800GT SLi setup. Yes, multi-GPU setups don't tend to scale well until you hit at least 1680x1050, though I'd trust that you'd probably be doing higher than that, and even at a bit lower than that, the SLi setup might be less efficient, but would still likely win in the end.

"they" being "him" meaning ME, lol... and no! for the second time the only time you get SLI is straight up, or if you're planning to get a second in like a week or a very small timeframe...
and if you look at that anandtech link, you will notice that even at 1280x1024 the 8800GT SLi still beat the GTX 280 which is 3 TIMES THE PRICE!!!!!!!! OH EM GEE.

WOW BRO! just what i was lookin for....dunny why the hell i didnt find it when i was googling...must have been too tired or somthin...
yep i know x8x8 sli isnt any difference at all over x16x16 for the 8800GT at least. i have done some research :)  that really is amazing that the 8800GT sli which is 2.5 times to 3 times cheaper than the GTX280 beats it hands down! :kaola: 
July 31, 2008 5:58:01 AM

wow i just looked at the COD4 bench there... single vs dual 8800GT is more than double the FPS! more than 100% scaling i didnt know that was possible! WOW...how is that possible? maybe just a fps spike or somethin... its only a small margin meh idk
