I always heard that if you have less than 4Megs Ram, then running 64bit
doesn't take advantage or won't see the Ram anyway, or something to that
affect?  I have dual core athlon with 64bit but only 2megs ram, which
under either/or, they only see 1.8 or 1.9Megs anyway.  So I just stayed
with the 32bit.
