I have the same mobo but with an Athlon 2100+. A while ago I concluded a cpu upgrade was pointless because I can only find suitable chips on Ebay, they are relatively expensive, and I'm not convinced I'd see the difference.
My next 'upgrade' will be to core 2 duo / pci-express DX10 graphics / DDR2 memory / SATA HDD's / Vista etc etc. ie a completely new pc
A good site I used recently to check for a similar upgrade click here Put your details where it says add comment and they reply within 24 hours with a recommended upgrade. Or yours may be on the list already.
