If budget will stretch, and you have the patience to wait for one, the Asus TOP is outstanding. I tried to get one recently, and gave up. As I understand it, they are having problems getting adequate quality components (don't know how true that is, or when that may ease). Other than that I'd have no argument with Tom's vote for the Gigabyte. Good quality, runs reasonable cool, and should overclock well. Evga are OK, and have good rep for after sales service, but not sure performance is all that special. Up until very recently, I would have said MSI Power Edition, but there are one or two concerns as to how they are achieving its performance, that have yet to be satisfactorily resolved.
