To be frank you can not dedicate a card I believe to handle tessellation geometry calculations, like you can with forcing PhysX on a single GPU. Also don't ever consider getting a fourth card for SLI/CFX setups, as scaling is horrible and the cards will heat up faster than you can say well "heat up"....
