If I put you in front of 2 identical machines, one running 32bit and
one 64bit software, would you be able to tell which one was which,

willing to bet that for the vast majority of applications you
wouldn't be.
That's a silly argument, because it simply relies on the fact that most
uses of computers aren't CPU-bound at all. In the same way I could
probably steal half the RAM from your system and clock the CPU down 50%
(the BOFH's favourite revenue-generating technique!) and from 'the
interactive performance of common applications' you wouldn't be able to
tell the difference. I don't think that _means_ very much, though.
It's quite meaningful, e.g. for power conservation. As you no doubt
are aware of, modern system regularly clock down the CPU.
