It's been a little over a month since Nvidia bought AGEIA Technologies... And what we've all known for a long time has now finally come to happen. No more physics cards.
The physics card as a hardware device will die. Nvidia spokespersons were very precise about that as they said that the current PhysX cards will be the first and the last of their kind.
