Win 7 32bit or 64 ?

General question from a noob builder.Does a mobo dictate whether its a 32 or 64 bit system ? I am doing a new build for one of my step children and was wondering what the difference was and which one to install. Any help will be great. Thank you.

More about 32bit
  1. The processor dictates whether it's 32- or 64-bit. You'll be hard-pressed to find a 32-bit processor nowadays apart from some very low-level ones (like the basic Atoms).
  2. Thanks. Is it possible to run a 32 bit on a 64 bit ?
