Question : Windows 7 32 bit vs 64 bit

Hi,
Am I right in saying that the processor determines whether you can install the 64 bit version of Windows 7?
Also, I am right in saying that if I go from a 32 bit XP or Vista to Windows 64 bit I will have to reinstall all the drivers?
Thanks,

If you're running a 32-bit version of Windows Vista, you can only upgrade to a 32-bit version of Windows 7. Similarly, if you are running a 64-bit version of Windows Vista, you can only upgrade to a 64-bit version of Windows 7. Otherwise, you'll need to use the Custom option to install Windows 7.
