I am looking to get a second computer so that I can run computer vs. computer
matches on one and do my work on the other. Currently I have a dual PIII 733,
and I can't work very well while two engines are eating up both cpus. It would
be cheaper to get a new single cpu Athlon to do my work on, and use my dual for
comp-comp games. The other way around (getting a new dual) doesn't make as much
sense, since my program doesn't support multiple cpus, and I want the faster one
to be used for my own program to play online.

I could build a decent Athlon system for around $400 or so, and that would be
good enough for developing and playing my program online, and then I could run
my engine-engine matches by letting my dual run for days :)

My program uses rotated bitboards (at least for now), but it's not the big
implementation that I usually see (512 KB tables). My tables only take up 64 KB,
so it would probably be beneficial to have the extra cache (512 KB), but not a
HUGE cache like the 8MB of some Sun machines.
