FSX does exist and I still love it. Unless you have lots of cash to spend on high end computers to deal with the massive files in MSFS, I, like most of you guys will be staying put. On a personal level, I admit that I'm a lazy writer, but I have extended my FSX sim to unbelievable standards, no stutters, aircraft performance improvements, scenery, water, terrain, weather,(realworld) in fact just about everything is enhanced, and all on a $450 computer, iG3 chip, NVidia 630GT graphic card, 4GB Ram.

Just out of interest, have you defragmented your hard drives recently? Another thing that I thought about is, is your Flight sim on a separate hard drive from the main operating system? Sometimes updates and various scans are taking place behind the scenes which could severely impact your FPS.
