Well for what it's worth, I've been using their 815 pro (model 6326 I think) with a PIII 933 for close to a year now. The board itself is pretty solid, the only problem that I occasionally have is when I power on the PC. Once in a while it doesn't post and hangs with the power and HDD LEDs lit, and I have to power down then back on again. Other than that, it's been problem-free.
