Hello. I bought a XFX 5850 Black editon gpu, but it seems that some games still lags a bit. like in Call of Duty 4, i maxed everthing, my fps was from 45-400. In Crysis i have 1680-1050 red, very high, no anti-alising. and the game did lag a bit. In Bad Company 2 i tried with 1920-1080 res, all set to high and Anti-Alising was a 4X and the game did lag. 3Dmark Vantage scores: GPU: About 10000 CPU: About 4500 Here is my system specs: Windows 7 Ultimate - 64 Bit Intel Core 2 Duo E6550 @ 2.33 ghz 2GB Buffalo DDR2 667 mhz XFX 5850 BE 550W Antec True Power 2.0 So i was wondering does my cpu bottleneck my gpu?
