Are people now moving on to nvidia cards for mining? I haven't followed closely for several years, but back in the day, it was all about AMD because nVidia's chips were much less efficient at this type of work. If nvidia is now in demand for mining, are people going for that because AMD is nowhere to be found and they're just going for the next-best thing, or has nvidia gotten better at this?
