S!
So I just slap in another 6970HD I have and good to go

The reviews claimed 6970HD to be hot and noisy as well, but I have NONE of those problems. I play World Of Tanks for a day and temps are max. 63'C and fan speed around 30-35%. Not really hot to me

In any game I have played the temps have never gone above 70'C for me. As said, use a GOOD and VENTILATED case that is placed so that airflow is not blocked.
Anyways..waiting more for Bulldozer, some preliminary tests have shown great performance
