Please help me get better performance!

Here is my current setup:
p3 1Ghz
512mb SDRAM
128 MB G-Force FX 5200 pci
What is the most important thing to upgrade to get a solid 17-18 fps w/ most graphics sliders maxed? I have an AGP slot, and I can still exchange the video card, only a week old. I would have to get a new case for my PC, which isnt a problem. Do I need more RAM? Does my vid card suck? Is my processor too slow for this software?
One other issue - my console doesnt appear in some planes, just a black panel where the gauges should be, although they are visible in virtual cockpit mode.
I'm new to this, and I am very excited about this game, but I can't enjoy it due to the poor performance of my machine. ALL HELP IS GREATLY APPRECIATED
