AFAIK, more than 1 GB RAM is only needed for ECM curves aiming at the 55+ digit levels and for "bigger" (I can't give exact numbers, but e.g. a 140 digit SNFS factorization is not big enough) NFS factorizations.

As an alternative, you could put in a faster CPU, which provides performances increases for basically every factoring method and target composite. Of course, you have to figure out what to do with the old CPU...

A more expensive approach would be to exchange CPU & motherboard for an Athlon64. But you'd probably also need Windows64 to take full advantage.
