Six 975X Enthusiast Motherboards for Today and Tomorrow

Asus P5WDG2-WS Premium Edition (w/ PCI-X)

Asus P5WDG2-WS Premium Edition.

The main difference between the P5WD2-E and the P5WDG2-WS is that the latter model targets the professional user and workstation segment. As a result, the P5WDG2-WS comes with two PCI-X-133 interfaces, and features an 8-phase voltage regulator. The downside is in the area of multimedia support - the audio chip supports only one rather then three Dolby modes.
