I don't think I would take NVIDIA advice from NVIDIA focus group.
As with any computer tech, there's no such thing has future proof. Especially video cards.
I would say buy the highest performing card that you can afford today, then upgrade 2 years later. I'm still using an Radeon X850 where I had to decide whether or not to get SM 2.0 or SM 3.0 and years later using this card, having SM 2.0 has not affected me. If I want SM 3.0 I would just update to a newer card, as most cards have SM 3.0 now.
My point is don't base your video card purchases on features that haven't matured yet, because by the time PhysX becomes mainstream your card will be like my current Radeon X850, slow.
