to be quite honest... I'd suggest just saving up for a new build...
I wouldn't pump very much money into such an old machine...
however, you could probably spend a tiny bit of money upping it to 1gb RAM. (which would definitely help system performance, for however long you have that machine)
even if you get a new (agp...) GPU and more RAM, I can't imagine the processor in that machine being qualified for any modern games...
At first, I want to suggest you to upgrade to a...say 7600GT and 1/2GB of ram, but then, a totally new build would last longer. your cpu, is it s939?If yes, a new build is better...
