I would stay away from it. I built a dual CPU xeon a year ago, and it was so expensive --you pay a premium for all of the parts, even the case is ridiculously overpriced. The worst thing was that one of my overclocked i7 machines was the same speed, or faster for 3D rendering.

Get a Sandy Bridge Intel(single CPU), and overclock it. Trust me as someone who has been there -- it's NOT worth it.

I'm pretty experienced with building machines and using them for serious graphical/editing work. That's my advice, hope you're willing to take it.
