Single core mode is important for debugging, that's why we keep it around, plus that it's more reliable and we haven't done the work of making state saves work stable on dual core yet.
When we get LLE audio up and running correctly, you'll find that having as many as three cores will be useful, since LLE audio will be very power demanding but can fairly easily be emulated on a separate core. So at that point, CPU, GFX and Audio will be on one core each. They can't really be split further, so I doubt we'll find much of a use for a fourth core..
