what is highest CPU to fit on EPOX 8RDA+?

[GratefullySaved]

Hey all,

I currently have an XP2100+ with 1 GB RAM, but would like to eventually get to some kind of equivalent performance as a P4 3Ghz and then double my RAM (for large file photoshop work - panoramas, large prints, posters, etc - things 300-700MB files I'm talkin about).

so...what options do I have to drop into my Epox 8RDA+ that I so dearly love and cherish?

Thanks for the help...
