I got the Asus GTX480, and have been pleasantly surprised after reading about the heat and noise. While it does get up to 91c, it never goes higher, and the fan never goes above 75%, so it actually doesn't get that loud. I know that heat level is pretty high, but it doesn't affect me directly or the system very much, and the card just kills in all my games.
Excellent Matto17secs i'm glad you're happy with it. Killer card which I think will fair better than 5870 in DX11 hence why I bought the 5970, I reckon the 5970 might just edge the 580 in DX11 until the 485 comes out that is.
