I have had this board since Feb2002 (1.8MP chips)! You should look at http://forums.2cpu.com. There is tons of information regarding this board (good/bad) to read. I set mine up as MPS multiprocessor HAL (i.e. no APCI) from the get-go and had very good luck with IRQ's and being able to capture audio and video through M-Audio Delta66 and firewire (respectively). I found the USB add-on card (have 1.03 Version board) a little flakey (but I've always found USB stuff a bit flakey no matter what computer). As far as I'm concerned, this is a very solid board with a nice set of features. I actually gave my system to my brother as I was looking for an excuse to purchase an AMD64 system. I will say that there is no substitue for a dual processor system if you do any rendering with it. THere are countless threads here and elsewhere that say dual processors are slower (for rendering times), but with a system that you're considering you can render in instance of Vegas, work in another, and work on something else - all at the same time. The smoothness and responsiveness is hard to give up once you've experienced it. My new system is an AMD64 3200+ and it's faster - but the dual 1800 MP wasn't much behind!

If you have more specific questions, shoot and I'll answer as best I can. BTW, my work system is a Asus A7M266D too (with dual 1800MP). Obviously I was impressed with the MB and processors!
