this card perform quite well under almost every circumstance . my win 7 64bit machine love it . the only problem be at installation . this card be freak HUGE . I have to literally remove part of the case to make this fit . but once it fit , this card work perfectly . no need to even overclock it to play almost every game i have at the highest of the high setting . it start to run into fram rate issue when I set Skyrim 's setting to the absolute most insane possible . 16x aa etc. . anyways , totally worth every penny since I be not a hard core gamer .
