"who knows, in the future the two might be combined?"

You can combine both today alreay and I experiment with it. The problem is still the high latency of the GPU. It takes ages, to get an answer and the timing is not consistent. That makes all scheduling for me a nightmare, when dividing jobs between the CPU and GPU. It would probably require a new hardware architectur, to make use of that in a sane way, so that GPU and CPU are more closely connected. (there are some designs aiming for this, as far as I know)
