Interesting, I've again had different experiences .
ASUS: Never had a good experience with any of their boards, the ones I've had have either clocked badly, or just died on my for no reason.
GIGABYTE: Have both the X58 and P55 UD5 boards now, and am quite liking them both. Although not having alot of success with the P55, although that may not be the boards fault.
BIOSTAR: Only other board I've really used, love them to bits
