As GPUs do really good work, it's better to sacrifice some cpu for the benefit of a GPU.
100% CPUs < 75% CPUs +1 GPU 97%

As Norton wrote - two 7970s . A i7-2600K like our Manofthem http://boincstats.com/en/stats/15/host/detail/2231226
can do +200K PPD with such a pair and others with 12 threads can do 230-260K PPD.
