I just started playing last night. It took me an hour to "tune" my Radeon 9800 Pro. I actually had to underclock it by about 15MHz on both the memory and accelerator due to overheating issues. Haven't benchmarked it but it still plays just fine on High Quality. Funny thing though, the sonund occasionally cuts out (Audigy 2) and I have to back out of the game and toggle the surround speakers setting to get the sound back on.
