I need more graphics processing for FSX. Would this 7800GS / 256M
-to-7950gt /512M
give me any noticeable improvement?

TIA

FSX's performance scales better with CPU improvement rather than GPU
improvement. That said, the GPU improvement you mention may allow for a
higher level of FSAA and ANISO filtering in FSX in your current
configuration at the same FPS you currently enjoy. It may not.
