If you do want to upgrade your machine, the #1 thing that I would recommend would be to add more system RAM.

That's usually the single biggest thing to speed stuff up, because once all your regular 256 MB is filled (which can happen fairly easily once you start building more complex objects and running more than one program at at time) Windows will start swapping chunks of memory back and forth to your hard disk which is so so much slower than having everything fit in RAM.

An older machine can work pretty well, but it does help a lot to have the maximum amount of RAM that will fit on it.
