Yes. A re-install is recommended (but not exactly _required_) when
moving from a 32 bit platform to a 64 bit platform on x86. A total
re-install is only needed when changing achitectures (for example
if you move from i386 to sparc).

In "Windows" land you also have to consider if you are _allowed_
to re-install on different hardware... ;-)

If you are on amd64, and the new CPU is amd64 as well, no need
to reinstall. In fact, I have a special FreeBSD HDD which I have
already booted on more than 10 totally different systems. :-)
