Correct. On the AMD side, 64-bit processors use a different socket
type than the 32-bits.

Now, as far as development goes, there's nothing to say you can't
develop on a 32-bit and use it on a 64-bit or vice versa.

As a side note, you don't need a new version of Windows. XP Home works
with 1 64-bit processor, and XP Pro works with 2 64bit processors. It
treats each as if it was "Hyper-threading" enabled, and allows you
specify which logical processor you want to run processes / threads
on.

There's no real new schema increase other than the socket type (and
PCI Express on some boards) so other than that the old hardware should
be reusable.
