It is very unlikely you would be able to get a processor that is noticeably faster.
It uses the slower memory PC1600-PC2100, which is almost unused today (PC3200 or PC4200 with DDR2 is the latest).
You have so much memory that adding more is not going to even be noticeable.
Your system is topped out, anything you do besides replace it will pretty much get you nowhere, at least by saying no where ...what I mean is you won't really notice any performance change.
