A 480 just for PhysX? Seems like such a waste...

This vid should give you some perspective OP:

Thats a single 580 Booty, if you have another 580 its going to render frames nearly twice as fast, which means twice the physx load (I believe). My 9800GT did much better when I only had a single 470, however with two there is almost no difference because the bottleneck my 9800GT creates just reduces SLI usage to around 38% at its worse, which would be close to 76% usage from a single card which sounds about right if my memory serves me correct.

Hmm, possibly. In that case though, it seems like it would be better to just let the 580s handle it than buying a high end 400 series.
