I think that's why Just Cause 2's performance is somewhat disappointing even on a 480GTX. The developer's choice to use CUDA instead of Physx meant that the water effects can't be offloaded to a GPU that was just dedicated to physics calculations.
Not if your at higher resoultions with alot of everything on higher settings, three is better than two.
