I have an older agp only machine with AMD 2600+ / 2G ram /266FSB /500W
supply

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

Like the other poster said, your bigger problem is the 1.9Ghz AMD 2600+
processor. You'll see a small gain, but the money would be better spent on a
major CPU/mainboard, PCI-e and RAM upgrade. Unfortunately, it costs more but
is FSX is your primary entertainment it's the way to go.
