In the fedora repo, install a app called  ailurus, open app and click on 
tab "information"  and  scroll down to where you see  "64 bit CPU?"  if 
it says Yes! you do
have a 32/64 .

There is still a lot 32 apps out there you can't run on a 64 bit install.
That is why I went back to 32 bit apps on my 32/64 box.

The dual, triple core CPU's run 32/64 bits
