When I investigated this recently, I came to the conclusion that for a chess
program, any of the AMD 64-bit cpus will probably be about equal. The main
differences between the Athlon64, Athlon64 FX, and Opteron seem to be along the
lines of memory bandwidth, and the FX has some extra stuff that should make real
time multimedia applications better (mainly 3D games and that sort of thing). Of
course, the FX is pretty expensive too. You might get that 10% speed increase,
but you said you don't want to pay double for it, so I'd pass on that one.

I would just get the highest clock speed you can afford. Memory bandwidth has
never been very important for chess programs, and that seems to be the main
difference between the various AMD 64-bit cpus. Of course, if you're getting a
dual, I think that limits you to the Opteron (no Athlon 64 or FX). Be sure to
get the 200 series if you get a dual, and a 100 series if you get a single cpu
(ex. an Opteron 148 is for a single cpu machine, while a 248 is for a dual, 848
is for an 8-cpu machine).

gcc will. The Intel compiler is free for linux, but I don't think it will
compile 64-bit code (well, it will compile for the Itanium). I'm almost sure the
new Microsoft compiler will (.NET 2004?). I don't know if it is officially
released yet or not.

You could always dual boot if necessary (if, for instance, you wanted to use the
Microsoft compiler and also have Linux for your other scientific programs).

I have no idea about the motherboards either.
