nope it won't.
The plan is to add in low end cards (8400GS and the like, can be bought very cheaply, worlds cheaper than a PhysX card actually) for all additional stuff or of you have SLI using one for graphics and the other for physics and other stuff.
You can naturally run it parallel on the same card as well but I don't think game designers will do that unless they do casual game designing with medium graphics and using the rest of the GPU for usefull stuff. But otherwise you will just offload it on core 2 if present etc.
