Thats not quite true, unless the 3060 Ti counts as a high end card I guess. It was easily the most popular mining card of the 3000 generation, due its excellent MH/Watt compared to the others? And previous to that, the mid-range 5700 from AMD was the best, to the point where you could sell your 5700 to a miner and buy a new 6700 and have cash left over at some points.
