Maybe, but if they strapped these with 64gb+ wouldn’t that be wasted on folks buying it for its intended purpose? Gaming. Though the “intended use” is changing and has been for a bit now.
One normally uses some ultra texture pack to utilize current gen card's memory fully on many games.
PC gamers would say that a modern mid-range card (1440p card) should really have 16GB of vram. So a 5060 or even a 5070 with less than that amount is kind of silly.
