Not necessarily. I was putting imaginary builds like this together in 2007 when I first started thinking about building computers. I knew how to pick the parts, but I had no idea how to put them together at the time.
I just noticed, isn't that board just compatible with Xeon CPU's? Even if 3960x is socket 2011, if I remember correctly, that board would only work with Xeons... though I could be wrong anyway.
Quad SLI 690's, I believe, would nearly reach 1,500watts on their own. So if you add in the other components, you might be a tad close to the PSU limits, if not, definitely over it. IDK how much a Quadro usually draw from the PSU.. (I'm too lazy to look to Google it LOL).
