Let me agree completely, without PAE you can only have 4GB physical memory, and 
even that is not used optimally. There are a few other things changed which are 
not of interest to most people, but in general if your CPU has the feature you 
should use it.

The article gives a bunch of detail, but the bottom line is that your system 
works and better and can use more memory.
