I'd need to know just a bit more to give my best answer--could you list some stats, like CPU model, etc?
Unfortunately, I'd say your best bet is to upgrade to Windows 7, and THEN look at hardware changes. Windows XP was definitely an awesome OS, but is soon to be put on the list of "legacy" operating systems, as Microsoft will officially be no longer supporting it this April. If you are still actively using it right now, I'm going to assume that some of your hardware is getting pretty old too.
However, if you're looking for the cheapest option to make it work, I'd just need to know more about your PC specs to give good advice.
