I had been in the same situation half a year ago, and I decided for a compromise and bought a Quad Nehalem (2011 model). This is a cheaper model, which means, less time needed for return of investment, and I can upgrade earlier, if needed, as the direction of PT and MacPro is hard to predict. It is a bit unclear, what's the best strategy, but if you have to work with your system (as I have), I do not care about "wait and see", but try to find the most reasonable constellation. If the mac gets payed in less time, it gives you the possibility to reevaluate your situation sooner.
