Hmmm, the ASUS P7P55 WS SuperComputer could possibly be very misnamed. It lists itself as a workstation system, yet it is more than capable of operating (very well) in a consumer level system. It is very versatile with the extra lanes for either SLI/Crossfire or for multiple Tesla cards. No matter what direction you want to go, the P7P55 WS seems suited to the task.
The layout is utilitarian and fairly clean. The extra two USB ports will be great for people that have to use security dongles for work (LightWave 3D and others). The HDD performance seems tailored to Audio and Video work. It just is a good all-around board. Even the $229 price tag puts it in the reach of most consumers looking for a good hard working motherboard. Overclocking was simple and yielded good results with the use of either manual controls or the TurboV software.
I really cannot think of anything that would steer me away from this board. It reminds me of the P5E64 WS Evolution. I still used this board until very recently as it was just that good. I think I have found its replacement in terms of performance, quality and reliability.
If you are in the market for a workhorse that has some power under the hood then the P7P55 WS SuperComputer should be at the top of your very short list.
