For some types of work flow you get very good linear scaling with
additional cores. Those include many data processing tasks (image
processing, rendering, encoding, etc.). Of course bandwidth in other
parts of the system can offset gains.

Leopard also added much better thread to processor affinity (it now
better understands the core / cache topology of the system).
