Having just faced this myself, a new build is the best answer. But if your shoestring just doesn't stretch that far, you want to find the fastest two or three cpu's your motherboard will support (check the last manf's bios update) and then haunt ebay or craigslist - or even better, a local enthusiast's garbage can - to snag that processor. Google up overclocking recs for those processors by name to see if any particular one was good in the day for over clocking. And if you don't have one already, there is also a bundle of good-for-thier-time AGP vid cards that should be able to be had for postage. And I still don't know if that will give you anything really usable (what good is a xp 2600+ and a TNT2 based card nowadays?); could be a waste of money - 4 fps is twice as fast as 2 fps but it's still unplayable crap. On the other hand, I have a few games unopened on my shelf from 3 years ago I'd love to play that would do just fine on it (ah, the joys of being old with money, yet no time...).
