My buddy has two 7900gs (i think) and i have a single 8800gtx. Assuming the systems are identical which would run better in games and a benchmark program?
Oblivion @ 1920x1200 res, you can choose a more preferrable resolution though if you want to, but this definetly accentuates the difference in performance, especially if you really want to push the cards in DX9... the one of the most noticable differences here though, is simply the amount of gpu memory needed for good performance at that res... so an 8800GTX completely destroys it then as you can see below (200%/3x faster), at a lower res though, the difference isnt quite as drastic, because as soon as youre above 20fps, gameplay becomes much more tolerable
they didnt have the 7900GS to choose from in the sli charts, but its essentially an oc'd 7800gt, so i chose 7800GTs in sli instead, for a close indication
GTX hands down. The GTXs are supreme, I wish I had enough money to get one when I built my system way back when. Now try 2 GTXs in SLI, now that's outrageous!
