From the Head mounted displays that I've worked with, the optics portion tends to be the limiting factor for dimensionality and weight. It isn't like going with just a GPU on the thing is going to make it into a set of eyeglasses. You've also got a lot of overlap in passing/processing video and general information passing/processing.
