Mason gives some good advice here. FSX definitely works better in the 4.0GHZ area, but another thing to consider for future use is 4GB of Vram on the video card you purchase. 64 bit X-Plane 10.3 now requires it for the new HDGLOBAL scenery, and it is AMAZING! While FSX is more CPU intensive more scenery is coming out monthly and there are plans for new 64 bit flight simulation software to be developed...so future proof your machine as much as possible.
