The XP on an AMD CPU is just a marketing gimick.  You should do great with
an AMD XP on linux.

The XP CPUs use less power and generate less heat then their predecessors, but
I don't know how it compares to the P4.

As I understand it, the performance boost in a dual cpu operating system is 
when the total output of both CPU's is greater than that which can be 
achieved by one CPU.  Given the choice, I would take the single 800 
because a single application that is not multiprocessor capable will be able
to run twice as fast where as on a dual 400 system, one CPU would be
100% while the other one might be idle.  There are additional factors 
such as throughput on both CPUs vs the single CPU, but I would opt
for the latter.
