Certain things will be faster on 64-bit. I saw benchmarks for web
applications using Apache that were noticeably faster on 64-bit than on
32-bit on the same hardware.

I can't say for sure. Perhaps.

The part that concerns me is how you can upgrade from 32 to 64 without a

If so, what kind of hardware should I be looking at, processor-wise and how

Use a bootable CD distro (any distro will do). Drop to a shell, then run:

cat /proc/cpuinfo

Look at the "flags" line. If you have "lm", then it is Long Mode, meaning it
is 64 bits.
