Yes, but a 32-bit OS still can't use it. Or can it?
Yes the OS can, but single apps will usually still see <= 4Gbytes, unless
they do a lot of (slow) black magic. Therefore, if you need a lot of memory
overall because you need to run a huge number of processes, 32-bit+PAE may
be ok; if you need a single big app to address a lot of memory
transparently, you need a 64-bit OS. I do (big quantum chemistry
calculations), your mileage may vary.
