I only would give the 3.2GHz P4 a slight edge because Peter and I compared his A64 with mine A-XT with the same Crafty executable. Mine was a bit faster (interesting enough it was proportional to my additional real clock speed). I compare my comp @2.5GHz usually with a P4 3.2 - 3.4 GHz. Thats why I think the P4 - 3.2 might have a slight edge! Lets hope Peter give it a try! Ingo
