Hi Tech Legion posted a review on the Gigabyte 890GPA-UD3H USB and SATA 3.0 Motherboard

The Gigabyte 890GPA-UD3H will showcase both the AMD 890GX Northbridge and 850 Southbridge chipsets. The Gigabyte 890 motherboard will utilize the native SATA 3.0 technology, as well as USB 3.0, which is the NEC USB 3.0 controller. It is also ATI CrossFire and Hybrid compatible with one PCI-e 2.0 X16 and one X8 slot. With its USB 3.0 controller, transfer rates of up to 5Gb/s can be achieved, making it up to 10x faster than USB 2.0. The native SATA 3 forgoes the Marvel controller (3^rd party) that we have seen on some Intel motherboards and has the potential of up to 6Gb/s transfer rates via the AMD 850 Southbridge chipset.
