Wow, this is indeed the mother of all threads. I am just assembling my system now, hope to mildly OC to maybe 9 x 400/425 on air.
One thing I learned while installing Vista64... DO NOT INSTALL EPU DRIVERS OR THE AI SUITE from the disk that comes with the MoBo. It turns your keyboard into a lethal weapon, causing numerous applications to freeze up in Vista. Go to the ASUS website, and find the latest AI Suite there (version 15, I think). I have come across a few posts in this forum from other users who have encountered this problem, but it definitely merits repeating because I was stumped for two days trying to figure out what was happening.
