Intel might be dicking around on USB 3.0, but Asus ain't. The Xtreme Design P7P55D-E is apparently the very first USB 3.0 motherboard. It's an Intel P55-based mobo that uses a third-party USB 3.0 controller for a pair of ports.
It has 10 USB 2.0 orifices too. Personally, I'd just wait for a full USB 3.0 board, where every port's USB 3.0. Otherwise, you're just gonna feel cramped and then dumb, when you have to buy another board. If you must have the 3.0 now this slab supports CrossFire and SLI with a pair of PCIe x 16 slots, a pair of Gigabit ethernet ports, and eSATA. Of course, there's no price or date for this thing yet, which makes it a little less exciting, perhaps. As exciting as gimped USB 3.0 motherboards can get, anyway.
