Nvidia's acquisition of Ageia in 2008 was a strategic move to boost the marketability of its GPU offerings. With the discontinuation of the dedicated PhyX boards, the acceleration moved to the GeForce GPU as a differentiation factor that set it apart from AMD's ATI cards. If a PhysX game detected the presence of an Nvidia GPU, it would move the hardware physics to the video card. Without an Nvidia board, the physics would hit the CPU, which in all cases is slower than what a GPU can do. (source: tomshardware.com)
