For last 5 days I have:
mother M3A,
6400+,
4 gig,
4870 x2,
vista 64 prem,
sb x-fi exgamer,
First 2 days were nightmare as I play AOC and continually every 10 - 30 minutes bsod and ctd due to memeory leak to point game totally unplayable Hour after hour checking and reinstalling. Finally day 3, took out my sb x-fi, replaced with onboard realtek 2.02 drivers just released and all my problems stopped. Can now played flawlessly on max. everything except for occasional lag spikes. I am a very happy ATI customer considering I had nvidia for last 6 years...
