If you plan to install more than 3 GB of RAM you will need 64 bit Vista to
use it. If you already have 32 bit installed and don't need the RAM then
stick with 32 bit. On a new system I'd go with 64 bit just so you can
increase the RAM later. You can't upgrade 32 to 64 so if you add more RAM
you would have to backup your data, clean install 64 bit, install your
programs, restore your data. It's easier to start with 64 bit if you think
it may be needed in the future. That said, not all hardware and software is
compatible with 64 bit. Before you install 64 bit make very sure that any
hardware or software you can't live without is 64 bit compatible.
