Can you help me evaluate 2 computers for live looping purposes

[Rick Walker <looppool@cruzio.com>]

Tiger Direct just advertised this computer for a very low price.

Would this be a safe bet for live looping using the new AURISIS virtual 
EDP loop V software
and , say, Plogue Bidule?       I'd swap WIN XP , Service Pack 3 out for 
the VISTA
which I don't like,  but I"m curious all you computer literate guys and 
gals out there.

I know that years ago, people preferred INTEL machines to AMDs but I 
know that
much technology has ensued since then.
I'd appreciate your collective wisdom on this one.
Thanks,  Rick Walker

while we're at it,   how about this laptop that they also offered?    
I'd only loop with this machine
and have no other apps or internet on it.
