Cheers David. I'd love a newer processor but I still have the 2.4GHz left over from the death of my old Mobo, and I'm not exactly made of money. I survived with a PII 450 until a couple of months ago so I'm not quite ready to bin the new processor yet. I've ordered an Asus P4P800/Deluxe. Hopefully the old CPU will die on me and I'll be forced to buy a whizzy new one.
