From what ive read in the last few days the difference is minimal really. Justapost did a comparison where the 770/790 were nearly the same from what i could tell. Its prolly nothing more then different bios settings from board to board either hidden or accessable.

Hope this board can push the new opty well over 3ghz! Not much info on clocking this board or the new opty's to be found! This thread and the abit usa forums are about it...
