You can not eat a GPU, And if your not employed by the Chip/Gaming/Graphics industry a GPU will not pay your rent. AMD and Intel integrated graphics, with proper driver updates, may be useful for some light gaming, and may be affordable to the masses. What is going to bring the most GPU utilization in the future is the new trend towards heterogeneous computing, with OpenGL, direct compute, and other software that opens up the GPU to be used for more general purpose computing tasks. With stockbrokers, scientist, and others all needing all the processing power they can get their hands on. Imagine the disappointed gamers out there, waiting for the latest GPU only to learn their most desired GPU is out of stock because some large day trading outfit bought the entire chip fab's output just to get a few milliseconds jump on the stock market!
