    I have done some test during furmark. during games (mostly killing floor) my games are stuttering for like 0.5 seconds then they are fine. Its like the card is struggling to render some stuff. Just wandering if its my cpu. Shouldn't be. On furmark extremeburn with post efx i have a consistent 21fps. This test max's out 1 core(100%) and the other at 12%. While it was doing this i opened orthos and set it to stress cpu. With both cores at 100% no drop in fps. When i change the resolution to 800x600 fps goes up. Faulty card? I've changed every variable and nothing works. 2gb of corsair ram. 1333mhz @ 400mhz (ddr) 800mhz. Cpu fsb = 200fbs ram timings are good ratio is 1:2 was 3:10 but i changed it and that worked so i'm just wandering if i need more than 2gb of ram. I haven't heard of a gaming righ without 4gb ram tbh.
