Folks, the GTX 1070s 8GB coming with 2017 laptops are still good enough for literally any semi-professional, non-mining application out there, from machine learning to gaming. With a few hacks and the right hardware setup, they can still do not-so-clever professionals happy. Therefore, this is a full supply-demand problem, with Nvidia facing its first, real catch-22 maturity problem: how do they sell new GPUs to happy-with-1070 regulars like me?
This falls apart when you move to a 4k display. A 1070, a 4k display, hdr, and a new-ish game and you are lightyears from the 60fps that is a minimum for many gamers.
