77k is basically the boiling point of liquid nitrogen, and 10k is probably the same for liquid helium. Liquid nitrogen is in ample supply and is not difficult to manufacture, I suppose one could have a facility on site to produce it and use it immediately. It is going to be very energy intensive though... to answer your question, I struggle to think of a scenario where it would be better than buying more compute power. I suppose for stubbornly serial workloads... but I'm not sure what that could be? Running Crysis at 20k resolution?
