it has usb 3.0, which is something that EVERYONE should look for when buying a mobo and making a new rig since a lot of the usb will slowly become usb 3.0 now since its faster.
Thats the least of what you should look for, as the only devices that can use USB3.0 bandwidth effectively would be USB based SSD's who needs shuffle that much data around that can't afford to wait for a bit.
Power phases, Sata III (for SSD's), PCI-E Lanes, USB Ports on the back, warranty support, bios updates, fan headers, all probably come ahead of USB3.0
OP: is built in GPU off? do you clean driver installs between installations? Nvidia and ATI may not play nicely together. Have you run memest for several cycles? Test your HDD's.
