It depends on your hardware. Vista Ultimate x64 has a lot of built in
drivers. If your hardware will work with these drivers is impossible to tell
without a lot more information.
Be aware that you cannot do an upgrade install from 32 bit to 64 bit. You
will have to backup your data, perform a clean install wiping out the 32 bit
install, install your programs, then restore your data.
