I got the diamond radeon 7970 and its nice so far I max out every game, GW2, BF3, Torchlight 2, except in torchlight 2 I have 60fps cause of vsync but then randomly drops to 30fps but I read that thats a problem with co op so we'll see.
Think Im set for now
and no coil whining I read about that before buying and it got me nervous.
