my system:

AMD 3200+
1GB G.Skill Dual Channel DDR
DFI Infinity SLI
nVidia 7900GT PCI-e

upgrades:

AMD x2 4200+
extra 1GB Dual Channel DDR

anything else?

I think that this would be a good upgrade for you.
Then in a year or so get a DX10 card once DX10 comes out/if you want to mess with vista.

Decent cpu and 2Gb of ramage, that's a good upgrade.

Yeah, you're fine with those upgrades. CPU + RAM ftw!
