According to a series of articles by Doug Horton in Computer Pilot Magazine the single most important item as far as performance in FSX is the speed of your processor. In multicore processors that means Core 0 or the first core. The second core might chip in a little, but FSX was not designed with multicore processors in mind so hyperthreading isn't going to do much good. Maybe Lockheed/Martin will push Prepar3d over that hump if they haven't already.
