I'm inclined to say, "don't worry about PAE, use amd64 regardless."

The reason for this is ASLR (address space layout randomization).  ASLR
works better when you have a larger address space to work with, and
amd64 gives you that larger address space.

Plus of course amd64 is the more 'modern' architecture, which implies
that it will tend to get more developer attention.  With time, i386 will
probably be dropped just like 32-bit sparc was.
