Matches my impression.
Some people say the 64bit-registers are better used by applications that
do a lot of calculations.
OTOH 32bit-compiledapplications are smaller, so less stuff to read from 
disk so less disk i/o needed for bins than on 64bit.
Also drivers on x86 are said to be better tested than ones on 64bit,
running many servers on 64bit i cant say 32bit-drivers are better than
64bit-drivers.

Runs without problems, and if you plan to use virtualization/emulation
software you should opt for 64bit as host-system since most of those
software do only emulate 64bit-guests with 64bit running on the host
system.
