Thanks for the quick reply but I would like to stick to an Nvidia card. Any suggestions besides 570? I mainly play sc2 and maybe diablo 3 later. Would also like to be ready to play future game releases.
nVidia has already released the GTX 680 . More 6XX cards are bound to follow shortly , but I havent been following the nVidia roadmap .
The newer cards will be 28 nm , run much faster and use less power .
