> Could I ask, what is the benefit of 64 bits compared to 32 bits for windows ?

In emacs I count things that total more than a 32-bit counter can hold, and I 
routinely edit multiple files of hundreds of megabytes.  Pure 32-bit emacs on 
Windows simply can't do the former, and is v-e-r-r-y slow at the latter, to the 
point of being unusable.  As a 64-bit program it does just fine, and overall it 
is, as Eli has point out, a whole lot faster.  64-bit Windows builds came along 
just in time to save me enormous effort programming around the limitations of 
the 32-bit version.
