Not to nitpick, but the limit in 32bit winXP/Vista is 4GB less the
MMIO region from ~3-4GB. In practical terms it's around 3-3.2GB. But
that's not your question :)

If you're buying a new machine, you'd actually be hard pressed *not*
to buy what most consider a multi-processor system. Multicore is
where it's at these days. (Intel will stop selling single core chips
early next year.) Will you benefit much in IDL? Hard to say.
Theoretically you could use the IDLtoIDL bridge and start multiple
instances of IDL and run those parallel tasks. How much of a
performance gain you'll realize would depend on a number of factors
but since you basically get that second core for free there's no
reason not to.

So go crazy and get that dual or quad core system.
