you can not just stick RAM in a computer and it works at 667MHz
the processor must be a 1333 FSB processor for 667 Ram to work without clocking. A 1066 FSB processor uses 533 RAM
Now if the processor gets changed, thats different
With a few changes the system can run FS9 or FSX. ..the changes that need to be made are processor, memory and video card and probably power supply too
Since its FS9 you dont need a Quad core so a dual will do the job just fine and if you use FSX this is also a decent little CPU solution
A E8500 Core 2

So if you do not have any use for 4GB of memory, then its a waste
The OS.. if its not 64bit and is XP 32 or Vista 32 you must edit the OS to not OOM using more the 2GB. That is listed in the FSX forum at the top of the forum in my tuning thread
Video card...

You will need at least a 650watt PSU to run the proc and the video card
