that sucks Aussie how stupid are they.

Crosshair booted just fine, but I couldn't login to windows.. BSOD.

Mustn't be happy with the new bus devices being detected.. perhaps a conflict somewhere..

An important thing I guess.. Do a clean install if upgrading from a dual, though it did work OK going from K8-K10 on the 790FX, a lot of new devices were detected.
