Hehe, SUN had terrible trouble when moving to 64 bit hardware, because
the users noticed the 32 bit apps ran quicker, the reason was quite
simply the extra demands on CPU cache that doubling everything made.

It should come into it's own if you ever have more than 4 GB of RAM!

The CPUs themselves are fast, so it'll be faster, but 64 bit addressing,
and instructions has taken a long time in coming, in part that we are
only just getting to the limits of 32bit. I mean how many people could
afford more than 4GB of RAM a few years back?

With many processors there are often things they are specifically good
at aside from just the addressing, typically it is things like
multimedia features, you want to make sure those applications are
optimised for the hardware if you care about things like DVD playback. I
have a machine here that has various multimedia hardware features for
which Alan Cox had done some special drivers, but these weren't in the
distros when I bought the box.
