Looking to upgrade and want to know which of the 2 is better, I've been looking for reviews or benchmarks that compare them but haven't found any : (. I want to run CoD4 at 1024x768 resolution.

Thanks in advance

You mean this benchmark (7950 GT 512MB vs 8800GT OC): http://www23.tomshardware.com/grap [...] &chart=275

8800GT wins by a long shot, but I could have told you that w/o the benchmark.

Well the 8800GT 256 isnt out yet, if the specs of it are like the 512MB version,(with the exception of memory) then it destroys the 7950GT

also if the specs of 256 comes out different compared to 512MB version,i would still think (for %99) that 8800GT 256 will beat a 7950GT (for %99)

Sorry - I rushed and picked the 512MB version on the benchy. After a little poking around though... check this out!

The 256MB version scores pretty close the 512MB version of the GT (until the really high resolutions) I'd have agree with Maziar, and say that the 256MB version will still beat the 7950.

Thanx MrsBytch for clearing it up

well as i see it has same Stream Processors as the 512MB version (112), so definitely go for it , it destroys a 7950GT

Go with the 8800GT.It's by far the best of those two cards.I do recommend getting the 512 version of the 8800,but only so you'll not have to upgrade later.The 256 version is just as fast as the 512,until you get to higher resolutions like anything over 1600X1200.Then the extra memory shows itself off quite nicely.Goodluck.I just got an EVGA 8800GT SUPERCLOCKED,650/1900 CORE/MEM.and it gets higher frames than my 7950GX2.Yes I do own one of the GX2 series,I also own a 7950GT KO,2 7800GTs,and a 6600GT.And of all the cards I have,the 8800GT spanks them all hands down.Only my GX2 comes close,and even that is still not quite good enough.

8800Gt will wipe the floor with the 7950Gt

It will wax and buff the floor with it too.

I have a 7900GT 256 and run CoD4 at 1024x768 with 8xAF and 2xAA detail medium, water detail low (not much water in the game anyways) and it runs perfectly at over 50 fps. I can tell the difference between no AA and 2xAA at 1024x768. My cards take too much of a hit if I go 4xAA or 1280x1024.

You definitely want a 8800GT 256 and crank up resolution and detail to or under 1600x1200.

8800GT

The 8800GT for sure. Shoot, even the HD3850 256MB absolutely destroys the 7950GT. Have a look. http://www.anandtech.com/video/sho [...] i=3151&p=9

Crysis it's over 100% faster! UT3 even higher. And most games at 19x12 res it's 100% faster. Not bad for $160ish. http://www.bestbuy.com/site/olspag [...] 4053242019

rofl! I just sold my GX2 for almost the same price as the new 512MB 8800gt costs! I spent $50 to upgrade from my 7950 gx2 to the 8800gt sc. The 8800gt is not only faster but it makes the GX2 look like a wuss. That GX2 of mine had so many problems no wonder they discontinued it so fast. That card never ever played any games smooth like this GT! I will never buy a dual gpu card again! NEVER! I could have gotten more for that gx2 if I sold it 3 weeks earlier making it almost a free trade, but an idiot at EVGA(out of respect for EVGA, not all our idiots but that guy I spoke to that day was) told me on the phone the day the 8800gt was released it's not worth upgrading from a GX2 to a 8800gt. I will never take advice from them again about comparing cards. It took me 3 weeks to finally learn from reading all over this card is a monster and after all was WELL WORTH selling my gx2. GX2's just have a terrible rendering problem when it comes to being smooth, they're fast but choppy-fast, not liquid smooth fast like this wonderful 8800GT sc.

8800GT has more future possibilities, DX10. Also its faster

Ya but you gotta remember how far back the 7950 goes...hell, ati had no cards that would compete with this monster and now you're comparing a classic to a newbie....I think you should neal before the alter of geforce and repent from your sins!
