I mean, jeez...for a game that was released 6+ years ago, I've never seen any other game run at such slow frame rates maxed-out--not even Crysis.
You pretty much need alien technology to run Flight Sim X in all its glory and still achieve a decent FPS, like 30-40. Anybody with me on this?
You might be right. From all I read, FSX is very cpu intensive, and can benefit from multiple cores.
If you want to optimize your FXS experience, I suggest you fisit some FSX specific forums. There is more to FSX performance than just hardware.
You will get more informed answers than you will get here.
