HI,I'm curious to know how some CPU's compare to others, mainly, when it comes to the frequency vs. multiple cores. In other words how would a single or dual core rated at say 3.00 GHz compare to a quad core rated at only 2.4 or 2.6 GHz. Do multiple cores running at a lower freq do better than CPU's with less cores running at higher freqs. Must be some advantage to having a multiple core CPU.My concern is in trying to decide which to get to run FSX.Thanks for any insight.Jim

4 cores running at 2.4 GHz with a 1066 MHz FSB will easily outstrip 2 cores running at 3.0 GHz with a 1333 MHz FSB. More cores means FSX and the OS can spread out the OS tasks and FSX's needs are not bottlenecked. Plus, you can overclock a quad-core for supreme performance.

FSX mainly uses the extra cores for scenery loading, so a 4 core will make that smoother (less stutters) than a 2 core but a E6850 will easily out pace a stock Q6600 as far as overall performance is concerned. Also a 2 core can be OC'd greater then a 4 core, due to the higher heat the 4 cores use.
