What can I upgrade pentium r 4 cpu 3.20GHZ with?

Need the motherboard model to know for sure but since that is a Pentium 4 it does not look like you can do much at all. Hardware is too old.

maybe a pentium 4 3.4 Ghz... :koala:

Just kidding,

but on a more serious note, your probably, no definetely better off getting a new mobo, which also means new ram, and then you think why not a new hard drive, and then you basically buy a new PC.

quite cheap these days anyways
