this card do surprisingly well when compare to the gtx 570 and the gtx 580 . First off , this be a giant improvement from my ATI 4890 and even my Sapphire Radeon 6870 . this card beg to be overclock and at the moment I be run it at 850\/1700\/2100 at stock voltage . I have see other people overclock this thing to 950mhz and above . it run every game I have on ultra with framerate above and around 60 fp , include bf3 and crysis 2 -lrb- dx11 ultra package -rrb- . the only thing I would recommend to check be case clearance -lrb- this sucker be huge -rrb- and proper cooling and adequate power . it be a pretty good deal to get this at $ 300 and get the performance of a 570 or almost a 580 if you overclock it properly . even at stock setting this card be right behind the 570 and I could still play my game on the highest setting without issue . tl ; dr buy this card if you be look to upgrade !
