ASRock P55M Pro Motherboard
 

For one of the cheapest boards on the new chipset, this one looks very decent. If you don't need 6 expansion slots and fully-fledged SLI/CrossFire, then ASRock P55M Pro is a nice choice for an inexpensive machine based on a Core i5 CPU (or future Socket 1156 processors).
