Software needs to be optimized to work on more than one core (or CPU). Most software is not, Ableton Live version 6.0 is. If you run e.g. Live 5.0 on a dual core machine, then it (and all of its plugins) will only make use of one core. This may still give you a performance improvement over a single core of the same type, because your driver stack might be running on the other core.
