About to upgrade, need advice!

Hi guys
Im soon about to upgrade my computer abit, and im wondering what should i upgrade?
I play Alot of pc games, so what should you guys recommend that i upgrade for better gaming?
My specs:

Ms xp sp2
amd athlon 3400+ 2200mhz
nvidia geforce 6600 256 mt
1 gb RAM

The price should be around 150-250 € (almost same as dollar)

And how do i know it it fits my computer/mother/main board and if i get a new cpu, how do i know it "matches" or works with my other 3d card, memory and so on...
Thanx, Filip

allright i tried that, now i know what memory works with my system.
Now... based on my specs, what would you do if you wanted to play games with higher settings? what would u upgrade?

What is your motherboard make/model?

Should be able to figure out a lot more of what you can do with this info...

I'd upgrade to 2GB of RAM.
