What are the issues with PAE?
Not all 32-bit drivers are PAE-safe. Even though the kernel can map memory above 4 GB for programs to use, some drivers can't handle memory addresses that are above the 4 GB barriere, and will cause hiccups, memory corruption, system instability, and so on.

And even if the drivers can handle PAE, each application is still limited to 4 GB of virtual address space. PAE just lets you run multiple apps each with their own 4 GB space.

PAE is really quite a hack. If you need to access more than 4 GB of RAM, go with a 64-bit OS.
