There is a big difference. You most likely aren't running with
software compiled for 64-bit, or software that wasn't designed to take
advantage of 64-bit, rather targeting 32-bit and just praying the
compiler helps with the 64-bit part. It gets a bit technical, but
there is a big difference between something made from the ground up as
64-bit versus something that was made 32-bit and just recompiled
64-bit.

Yes, with the unfairness of the compiler, that is true. It's a lot
like if you had a car that could go 200MPH. Your driver may only hit
80MPH (the 32-bit code on a 64-bit chip), but then you get a driver
trained for 200MPH driving, and then he actually hits 200MPH (the
64-bit code).
It's like the good data in good data out / bad data in bad data out theory.

Well, I think we must include bragging rights into our deliberation.
That's a major part of it, too. Even though some people may never use
more than a whole MHz of their PC, they still like to brag ; )
PS: I'm not one of them. If there were a law against computer abuse,
I'd be locked up for life - It pains me to see a CPU idling.
