Erm.. thats a pretty daft thing to say. UEFI problems are not in anybodys head. Asus, and MSI are having issues, Gigabyte can't even make a UEFI. As for the Extreme4 at least, some of the UEFI problems that have been reported by a multitude of people are double boots before actually powering up, changing too many settings at once in AI Tweaker will cause the board to fail to POST (and thats even with leaving the multiplier at default), etc. Oh, and yes I've checked all components individually, their all fine, its a flaky UEFI.
