Streaming data to the GPU isn't a problem of interrupting it. GPUs use memory fences, atomics, and other things you might find in CPU land. Why are we in trouble if the demo was true? For every type of hardware, I can come up with a rendering algorithm and data set that makes it look better than similar hardware in a different configuration. If you have more memory bandwidth, you should be using it accordingly.
