mate that's the way it is - manufacturers have always given priority to releasing their card over fixing glitches, so they always take a while to get up and running properly. It's only been out 2 months anyway.
I set RIvatuner to sort my fan incrementally - about 35% i think, and i idle at 56c.
One problem i have randomly, is on Pro evolution 2009, I think my 4870x2 is creating a bottleneck, as the best GPU the game manual lists is a 3850. All settings are turned way up in CCC. Basically, when i play, every 8secs a slight disruption (line) moves up the screen. Hardly a problem but noticeable.
