Just looking for some opinions. I currently have a Socket 478 P4 Northwood 2.2GHZ CPU, 400mhzFSB. I believe I can overclock it relatively safely up to 2.93ghz. I have an ASUS mobo, so this is technically free. My other choice is to upgrade to a Prescott 3ghz and get the 800fsb and 1mb L2 cache, but it will run consideralbly hotter.
