ok see the game I play the most is Tom clancys hawx and man let me tell you, either this graphics card or the cpu is on its knees!!! I get like 5-10 frames per second!!! I honeslty thought this 460 would do the job guess not! and I also want to be able to turn up the settings to the max so what if I did 2 580's in sli? could my system handle? or better said my PSU?
