I've been building systems around MSI, GigaByte, Abit and Asus motherboards for close to 20 years - and this board is the best I've used yet. Great quality components used throughout, excellent cooling and power regulation features included to assist anyone interested in overclocking. The stand-out feature for me is Asus's excellent EFI BIOS implementation - which actually makes the config of the BIOS settings a real point and click pleasure that no longer looks like you're back in the MSDOS era!
Tonnes of SATA connectivity (8 internal, if memory serves me correctly + 1 external eSata) provide a good basis for a very expandable workstation pc - whilst internal Bluetooth also offers some interesting functionality not often seen in mainstream motherboards (works fine with my iPhone 4 and Nokia work phone for handsfree calling and wireless music streaming).
The board seems very stable And ASUS have already released an enhanced BIOS supporting additional CPUs - not bad for such a recent board.
