That's why I said it depends on how much the offload would be, for example, Wii U setup with a supposed weaker CPU. Nvidia does just fine with their stupid physx bullshit, I say stupid because they won't make it open to AMD GPUs and Hybrid PhysX has been put on hold since the dev's old ass Nvidia card broke. the APU+GPU setup would be a great setup though, then like you said, they can do physics on the APU's GPU and use it to assist the more powerful GPU in other areas as devs see fit, we just have no details yet.

I lost interest in following the PhysX stuff. It started with dedicated PPUs (Aegis or whatever it was called), dedicated graphic cards, then went to doing it in existing GPUs. The former solutions are too expensive for average Joe, the bechmarks I'd seen of the latter had (sometimes very) dramatic decreases in fps (no surprise here, and I think only a few games actaully tried it).
