The ASUS P5W64 WS Professional motherboard is an interesting contrast to their ASUS M2N32 WS Professional board. As a workstation class board, the P5W64 WS Professional has four video card slots, allowing 8 monitors to be attached to the computer at one time. This unfortunately does not leave room for the PCI-X slots that the other board has and limits the expansion options on the board otherwise. A Four-Way Crossfire configuration is a possibility according to AMD but is not possible at the moment with current available drivers. Hopefully this will be resolved soon, but this board is not geared at the gamer in any case.
The P5W64 WS Professional has mediocre performance and overclocking compared to its desktop counterparts. The side benefits of this motherboard include the ASUS advantages, AI Gear, AI Nap, AI NOS and the four video card slots. I took the opportunity to install an 8800GTX, two 7900GTs and a 6800GT in Quad video mode and the board booted up giving the possibility of 8 monitors. Unfortunately we did not have that many monitors free to test every connection out, but they did show up in the drivers screen. This is a great board for those seeking a workstation class motherboard that has multiple-monitor support. Stability and options are the P5W64 WS Pro's stand-out features. The lack of any PCI-X slots for 32-Bit SCSI may be daunting to those wanting to do video editing, but with SATA 2 at only a bit slower than the ultimate SCSI transfer rates available it's not much of a sacrifice.
