In general, I have heard 2 things about ALi Magik1 based mobos -
1. MBM doesn't work (see front page, apparently our very own Skip has been working with Alex Van Kaam to remedy this problem in a new beta version).
2. Performance lags behind AMD 760, Via KT266 and even some KT133A boards. Not good if you ask me. I wouldn't buy one, just one dude's opinion though. (granted, this comes from a guy running a KT133A board)
