I'll tell you one thing, this board sucks donkey balls when paired with a Quadcore.
If I go a hair past 3ghz (9x333fsb), my computer will restart, be it 15 minutes after I turn it on, or 4 hours. I'm planning on getting a P5B Deluxe to try find out what this Q6600 can really do, and putting my E6400 back in the P5N-E.
