if the mobo has PCIe slot, then maybe a HD 5670... if it's AGP mobo then it's not really worth to upgrade it, just get a completely new system. Even a relatively cheap modern rig will be tons faster than that old thing.
If PCI-E is avaliable, then go with a 5670. If not, your best bet is probably a 3000/4000 series AGP card...
