There is an oft debatable performance improvement.  I think
it's in the 
area of 10% on some applications (that are cpu bound). 
Other processes 
are reported to take a performance hit, and memory usage
increases

It's possible to create 32 bit chroot environments, or to
install a 
32-bit version of mplayer (and associated libraries) that
can use the 
w32codecs.  Not really worth the pain if all you want is a
working 
desktop with all the multimedia toys.

Press the '1' key when your in top to split up the CPU's. 
The GUI 
system monitor tools will do this as well. (I'm a big fan of
gkrellm myself)
