The Great Debate

Here's how it goes:
I am currently running:
P4@2.1 GHz
Radeon 9000pro
512mb PC2700 DDR
...basic specs.
Now, at Heathrow I normally get less than 10FPS(full sliders) no matter what plane, what weather in FS9. I really would like to get the FPS up to around 20 without sacrificing quality.
What I am thinking:
Either a 9700pro or 9800pro
Or
a 9600pro or 9600xt and another 512mb ram.
Now, could I get some advice, please?
(money is a non-issue)
Thanks!
