I hard disagree with one of your positions; I think 0 F is cold but 100 F is insane. I assume we grew up in different climates. I say this only to make the point that it’s subjective, but 0-100 is still the range of what people generally find tolerable.

1440p is the sweet spot. Very affordable these days to hit high FPS at 1440 including the monitors you need to drive it.

1080@120 is definitely low budget tier at this point.
