The main advantage of 64 bit is the ability to use more than 3GB of RAM. If
you have more then 3GB or plan on later installing more than 3GB then you
will need Vista x64. There is no way to upgrade from 32 bit to 64 bit. A
clean install is required meaning you have to backup your data, install
Vista x64, install your programs, then restore your data. Because of this,
if you think you may want Vista x64 at some point you're probably better to
install it now.
