I love my 9NPA Ultra. I went with it for the same reason as Doug, the DFI (so I've also read) is real picky about ram/power, etc. I'm still using a 20 pin 350 watt Antec PSU so I didn't want a mobo that wouldn't like it. So far no power probs, and I've yet to see prime95 fail at my current clock. Also, my PC stays on 24/7 running Folding @ Home.
