I was playing COD:MW3 on a 1440x900 screen on my friend's PC
CPU PII x4 840
GPU XFX HD5770
I couldnt play it in ultra. got around 35-40 fps.. but during levels where there was lots of smoke fps dropped and it started lagging. so i OC'ed the card to 890/1275 (stock is 850/1200) using CCC and the game is running fine at 40+fps.
Is my friend's card underperforming cuz i saw that HD5770 can play MW3(Ultra) at HD resolutions. And by ultra i mean everytihng maxed out AA, SSAO and all
