I want to increase the power that I have with my computer when playing games. I have a q9300 stock, 8gb of ram and 2 asus 8800gt 1gb video cards in sli and I still seem to get crappy fps. Would a video card upgrade be the best way to increase this like say up to a g280? Games I am speaking of are F.e.a.r. , cod4, and gow. The most I want to sli is 2 cards. I have a 780i mobo. Cooling is fine theres an AC right next to the tower. Any suggestions?
