I have a trusty PII 400 MHz, and an AMD 950 MHz machine.  I haven't really done much overclocking but I plan to do it to them this summer.  Anybody have any good sites for more info on overclocking?  Personally, I used to think that Intel was the bad boy on the block.  However, ever since AMD came out with their Athlon line they've made me switch.  It's just logical, you know?  AMD has their chips that'll perform just as well as Intel's for 3/4 the cost.
