Currently in the process of building a computer, mostly to run FSX on, but I'm not sure which processor to get. I'm not looking for whatever's more futureproof (because I know NOTHING is futureproof), just whatever will run FSX the best. i5 750 is a quad core (no hyperthreading) @ 2.66 Ghz, while the i7-860 is a quad (has hyperthreading) at 2.8Ghz. Let's say the i5 is overclocked to 2.8Ghz, will it run FSX as fast as the i7 would? I've heard that the i7's hyperthreading wouldn't do anything for FSX, as FSX can't utilize it. So which is best?
