I recently reinstalled my notebook, and my friend laughed at me because I didn't install the 64bit-version of vista instead of the 32bit one.
After which I wondered whether there was a great difference in performance with the 64 OS.
(I've always been sceptical about the 64bit version, because people used to tell me there were a lot of applications which didn't work anymore since they installed the 64bit version.)
So who can clear this up for me? :)
