Btw: rather than adding more RAM, I would consider an SSD - or even better: a Revo drive.

I don't know enough about Revo Drive's to recommend them, but I would suggest either buying yourself and SSD or building a Raid Array (or RevoDrives). When disk access is heavy, then that's the avenue that ought to be explored.
