Processor speed is not the entire key. A MB that has a bottleneck on the FSB is like death to Bryce. You need to match hardware. Make sure you have the BIOS configured right. I can make my athelon 550 sing faster than many intel 800's just by tweaking. That being the case, imagine what the right tweaking will do for a 1.2g. Oh, I'm an AMD fan and for many reasons. Just built a 1.2g / 266 server for work. Lightening fast on some things, slow on others. It depends on what the application needs and Bryce needs fast processor and wide open ram. You do the fast cpu and don't bottleneck the ram and you'll be running like a raped ape (and raped apes do run very fast). Just cuz you have a 1.2g AMD doesn't mean its running at 266 bus. You have to configure the bios and heaven forbid that you got a bad MB. I recognized a bad Gigabyte board second day the server was up. Took two experts and a week of tech support to confirm that. I'll never buy a Gigabyte board again, or any board that has software controlled bios settings. Put the settings on the chip or its outta here.
