This isn't any help -- don't know about the addition of the new hardware, but I had a dual where one cpu would hang and go into full use mode, or the processors would take turns being in full use mode. I had the computer in the shop to have the power supply upgraded and had them check the processor. It was faulty. Fortunately, it was still under my extended Applecare warranty.
