I had FPS problems with my computer also and I am running a Core 2 Quad processor.
I solved my problem by going into START>RUN (or hold the Windows flag key and hit "R"
Type in "msconfig" without the quotes and see what is running in the background under the "Services" and "Start Up" tabs.
Shut down programs that are obviously not required.  Don't worry about shutting something that you think may damage your computer.  Nothing that you shut down in "Services" or "Start-Up" can cause any damage to your computer.  If you select something that may damage your computer by not running, you will get a message.
Restart your computer and in Vista you won't get any message, but in Windows Xp you will get a message saying that you have "selective" starting active.  Just cancel out of that and start your flightsim.
See if it runs better.  If it does, you have a background program interfering and may want to play around starting programs one at a time until you find which, or if everything runs good, just leave it the way it is.
Note: Before installing new programs you will want to turn on the "Windows Installer" or you won't be able to uninstall them in the Control Panel.
I also found that because my gaming computer is the host on my network, I had to turn some network related programs back on and some Windows sound programs back on.  Other than that, I left everything else off and FSX runs great.
If you run into OOM errors, that is something else that can be fixed, but differently.
