Gigabyte GA-P55A-UD6 @ TweakTown

"GIGABYTE is one to do things big and one thing they wanted to be a part of first up is the SATA-III (6Gb/s) and USB 3.0 revolution. Now, whilst still considered premature as far as wide adoption goes, this is not a bad thing. After all, we already have USB 3.0 controller chips from NEC and SATA-III controller chips from Marvell starting to show their faces, which is extremely impressive."
