Look, IMO, while Dothan is an excellent chip, it can't compete with the A64 on a clock-for-clock basis. I ran some CPU intensive benchies on both my laptop (which has a 2.0GHz P-M 760, 533FSB) against my main computer at stock (an A64 Winnie 3200+), and the A64 was between 3-10% faster. That isn't much, mind you, but it is a difference.
