I'm looking for a CPU that will support PAE and fit into an LGA775 socket. This combination of technology is very much preferred for my current server hardware/software setup.

My priorities in order of highest to lowest:
PAE & LGA775
At least 1066Mhz FSB
Largest CPU cache possible
Multiple Cores if possible
HyperThreading if possible
Most other factors are of little-to-no consequence.

I'm finding it very difficult to figure out what my options are. Intel doesn't have much useful information on PAE (since x64 is so dominant), and Wikipedia simply says that "PAE is provided by Intel Pentium Pro (and above) CPUs - including all later Pentium-series processors except the 400 MHz bus versions of the Pentium M."

All of Intel's listed Pentium CPU's support Intel64, which makes me seriously doubt they will support PAE with a 32-bit OS. And Wikipedia's claim is so vague, I have no idea if they mean up-to-and-including the x64 Prescott CPUs. PAE is supposed to be an aspect of the x86 architecture, and I believe it is no longer supported in an x64 environment. Please correct me if I am wrong.
