I like my DFI Ultra Infinity. It's got 4 different bioses, so I can go from running at 2.5ghz (with all of the voltage & fsb tweaks that requires), to running at stock speed, in about 20 seconds. Plus, it has loads of overclocking options. Oh, and it was only $99 at newegg.😉
edit: And Alex is right, the A64 doesn't even have an fsb, the same way that all other chips have an fsb. That's the reason they will run so much higher.
