Multi-display on SLI, being able to possibly use 2 different types of cards with one being dedicated to physx, and performance optimizations. Can new drivers REALLY add that much performance? If they could, why wouldnt they rush them out when the 4XXX series was benching so well and avoid all the bad PR?
