I dunno. I've never had much luck with frequency scaling.
My guess is that this is the sort of idea (much like
micropartitioning & virtualization) that doesn't play well
with constant intensive usage.

My core duo frontend makes less noise and runs cooler when freq
scaling is turned off completely.

If given the choice between a 3200+ and a P4, definitely go with
the AMD chip. With a good nvidia card, the 3200+ will probably
be good enough to do anything you want with it, even including
reasonably fast h264 decoding.

The vidcard really does make a lot of difference in Myth.

...another odd bit of trivia: I have an old laptop that runs hotter
under XP than it does Ubuntu. Under XP it will run itself so hot that
it has to shut itself down.
