The Steam machine stats are absolutely pathetic by PC Master Race standards... but that's the thing--they are actually targetting the median Steam user and they have the data. I think the most common GPU is around a 2060 right now. We reached the start of the top of the S- curve a decade ago, at least.

Edit: Nope, it's 1060. Bwahahaha.

Edit: Ugh. It was a 1060 I guess when DDG was training it's AI. Currently 3060.
