buy two of these on release day . I upgrade from -lrb- 2 -rrb- AMD 5770 . I think those two be pretty fast as i could run most game at the highest setting . dx11 be out of the question though , so i have to settle w \/ dx9 or 10 . I have no idea these 680 would be this fast . I run several benchmark and record result - some benchmark be 800 % faster over my previous 5770 . I can run any game , all the highest setting , physx -lrb- if available -rrb- and everything be completely smooth . Metro 2033 , for instance , be a slideshow with high setting . now , i can run the game at 2048x1152 , physx , max setting , msaa , all dx11 feature enable . it be completely smooth . amazing . I cant fault these card at all . theyre quieter than my previous 5770 and run cooler . my system use less power now as well . for other ' reference , here 's my setup : core i7 920 @ 3.8 GHz Asus P6T OCZ 6gb ddr3 EVGA GTX 680 SLI OCZ Vertex 2 60gb , Intel X25-M 160GB Creative X-Fi Xtrememusic Silverstone 1200W Corsair Carbide 500r
