I currently run FS2K, Fly!, CFS, FUIII, all with acceptable frame rates.
My set-up is PII 350, 160mb Ram, 32mb TNT2.
All the hints & tips I have seen for all the various fltsims around emphasize RAM, RAM, RAM!
If you can get more system Ram, and a decent sized graphics card Ram, you shouldn't have to scrap your current processor(166mhz or faster).
Having said that, Ram is currently at a high price per mb.
