Wow thats insane. I don't think there is any way I could ever justify spending over $300 on a motherboard, let alone $500. Both the EVGA and XFX 790i motherboards are in the $370 range. Hard to believe that ASUS's 790i actually gives you $130 more performance/features. And you will also lose 99% of customer support.
