OCW posted a review on the Gigabyte GA-8I955X Royal motherboard

Pro, Ultra and now we have a new term "Royal". The Gigabyte GA-8I955X Royal deserves it as it is one of the most exciting package I have ever come across. In fact, among the manufacturers we have come across, Gigabyte implements some of the most exciting technology onto their boards. With the i955X chipset, it brings the board to another level with Dolby certified audio and Highly advanced Intel=AE Matrix Storage technology allows RAID 0 (Striping), RAID 1 (Mirroring), RAID 0+1 (Striping and Mirroring), and RAID 5 (Parity RAID). With the on board 2 additional SATA ports, you get another RAID 0/1 array. That is not the usual high end desktop board we are talking about. In fact, this board is more like an entry level workstation board, I would say. The Universal Plus Dual Power System (U-Plus D.P.S.) that not only helps to extend the lifespan of power modules by keeping them cooler, but also increases overall system reliability by being able to continue to operate even when one transistor has blown. This allows you to continue working on your PC without fail.
