If you don't expect any process to need more than 4G, or you're 
expecting to be limited in the total amount of RAM, a PAE kernel may be 
sufficient.  If RAM costs/space isn't an issue, you might as well go 64 
bit and be done with it.

Right now, my eight-year-old mobo's maxed out at 1G, although the CPU 
could handle 2.  I'm finally in a position to consider a hardware 
upgrade and expect to be migrating to 64 bit RSN.
