I tried a spare 2800 from another system for awhile.
It made little difference by itself.  Both the 2500
and 2800 are "Barton" cores and run at 333FSB with
512K cache.

I also have a "spare" AMD64-3200 and an nForce3 mobo I
could throw into the system.  Hmmm... I wonder if I'd
have to reinstall Linux or if it's close enough to
just put it in and boot...  I'm using KnoppMyth and I
have not recompiled anything for processor type (yet),
I'm just using the stock i686 debs for Linux and Myth
(except I did recompile mythfrontend).

Maybe I'll back up and just give it a go.  I'm not
feeling enough pain yet... :-)
