8800 GTS 320 SLI over single 640?

What would be the performance gain over a single 640 version, if any? Would SLI work on say the MSI P35 Neo2 FR (or any of the P35 chipset boards)? Or would the second slot bottleneck? I usually play at 1024 x 768 ocasionally 1280 x1024 max detail due to my 19' LG LCD monitor. My card now is a EVGA 7950 GX2 OC'd. Reason I'm asking is I'm building a second system, Intel based.

The 7950 is still a respectable card. I'd save the money for a future card and/or a better monitor (22' widescreen).

If your only gaming at 1280x1024, people will argue about what card to get (GTS 320mb vs. 640 mb), but I really like my 8800 gts 320mb.


EDIT: My bad. Didn't register that you were building a 2nd system.

In that case, I would not recommend SLI'ing 8800 gts 320mb's. Your better off spending that money on one GTX or GTS 640mb.

I have the Foxconn 8800 GTS 320 w/ factory oc. I play stalker, C&C 3 and HL 2 mods. I have a 19' lcd as well playing at 1280x1024. I can play all these games with eye candy turned on, no problem.

Also, take a look at Tom's GPU charts. You can see how the GTS 320mb did when SLI'd. Then find some reviews of the single 320mb cards and compare FPS for games.

If you stay at that resolution then your 7950 will work perfectly.
Unless you plan to go higher or get vista :wink:

SLIed 320 would certainly be more powerful than a single 640, but they would cost quite a bit more too. I would stick with 1 320MB for those resolutions. Incidentally, the 320MB don't combine to 640MB when SLIed, it's still only 320MB. Not sure if you were aware of that.

SLI'ed 320's will run most DX9 games a lot faster than a single 640, but with newer games needing more than 320mb of memory for textures the SLI setup would still start to struggle (as it'll be swapping out textures with main memory constantly - major bottleneck)

also, a 320 SLI build wouldn't run any quicker than a single GTX anyway, and two 320's will cost you more than a single GTX

Thanx everyone for your input. That's what I love about the forums here. I believe I'm going to go with the 640. I will be getting Vista in the next year, give or take a little, and I'm really looking forward to games like Bethesda's Fallout 3. If it's anything like Oblivion I'll need every bit of the 640 megs of ram. Heck that might not cut it either. 8O

The P35 motherboards support Crossfire (ATI) not SLI(nVidia), you need a nVidia 650i or 680i motherboard for SLI.

The 640 will work fine. And for oblivion too. :wink:

I wouldnt suggest either GTS as they want show a great enough improvement for the price. You would need to go for a GTX to get reasonable FPS increase for the price. Heres a massive benchmark show the differences from your GPU.

Its in another laugauge so just look at the charts and click on Nächste Seite at the bottem for the next page.

Pay attention to the 4FPS the GTS's beat your 7950GX2 at 1600x1200. Is 4FPS worth $250? This isn't always the case but some games even have the GX2 ahead by a few FPS.
http://www.computerbase.de/artikel/hardware/grafikkarte...

I would suggest you use your 7950GX2 a bit longer because I hear Nvidia is comming with 8900's this fall and the G92 by Xmas.

I think he is building up 2nd pc but not upgrading..

If you would like go for sli 8800 gts 320mb, I think it will be better to get a gtx.. sli 8800 320mb will not b faster than the gtx and the price of 2 gts will be more expensive.

True but he would be better off buying a cheap GPU for his old system and migrating his 7950GX2. Paying a lot for not a good improvement in FPS isnt going to make the OP happy. I agree the 8800GTX would be the better step up and would leave room for a future cheap 8800GTX SLI upgrade..
June 26, 2007 4:40:10 PM

well it's good idea too to get temp cheap gpu for his pc.. if he willing to wait until dx10 games bcome common. (for me i think i won't be able to wait lol)
June 26, 2007 5:37:16 PM

Ok I'll consider the cheaper gpu option. What would you all consider a good recommendation?
June 26, 2007 5:58:07 PM

SLi 8800GTS 320MB is always a bad idea.

Why?

The thing SLi is good for is high resolutions, (1600x1200 at a minimum imho) with lots of eye candy (AA/AF).

The GTS 320MB is fine at lower resolutions, but in 1600x1200 and above, the smaller RAM size becomes a limitation.

Therefore, there is no "good" scenario for 8800GTS 320MB SLi.

On the other hand, 8800GTS 640MB SLi, or 8800GTX SLi, is great for 1920x1200, 1920x1080, and 2560x1600.

Buy an EVGA 8800GTX or migrate your EVGA 7950GX2 to your new system. The migration plan works well knowing Nvidia is comming with 8900's this fall and finally G92 around Xmas.

If you need a cheap GPU in your old system just buy one of these or something cheaper should due fine.

Well I didn't want to put a super cheapy in. Something that will last a little while. I don't believe that 7300 will do very well against todays games. This system is for my boys and they like BF2 and BF2142, NWN2, Oblivion. F.E.A.R and the like. They play what dad plays :wink: What about this?

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

Maybe even 2 in SLI
But that's as much as a 8800GTS 32O OC. I don't know what do you guys think?

That 7900gs will work fine for the games you listed depending on what
resolution it will be pushing.

Ok so the old system is going to get a lot of use by your boys. The 7900GS is a little high priced. 7900GS are mostly $100 for a good deal. I would suggest a 8600GT for about $99. Take your pick the XFX and EVGA.

So what did you decide to get? Or what is the current question?

I wouldn't recommend sli'ing 7900's. Your better off buying a 8800 GTS 320mb
June 29, 2007 12:53:08 AM

I decided to get the 8800 GTS 640. It should last me a while. At least until the G92's are out and established.
June 29, 2007 1:21:10 AM

A 7900GS won't be fast enough for NWN2 and Oblivion at high qualities.
