i know it depends on hardware (age etc) but whats the fuss

A kernel with PAE extensions allows a 32bit kernel access to more than 4GB of RAM (actually more like 3.7GB).
(that includes ALL addressable memory, such as graphics card, etc.)

so if you have 4GB or more RAM, and you want to run a 32bit OS, you’ll want a kernel with PAE (Physical Address Extension) … or a 64bit OS, which doesn’t suffer the 4GB limit but does require a 64bit CPU.
