It's not a motherboard problem. How would you integrate support for user provisioned cooling options (to match cooler to the card wattage) and still keep any sort of flexible expansion slot area? GPUs can't be turned into a single chip, there's too much going on, so you're never going to have a CPU cooler situation. So, fine, what if you made them daughterboards mounted like M2 SSD's; that may work, except ATX now has to become ITX to give room for an extra board's worth of space. It's a PC case orthodoxy issue, really. People want plugs at the back of the box, which dictates how the GPU must sit in the case, and disagreement on GPU sizing means no brackets. Solve these two issues and life gets a lot better. Or, solve it like SFF case guys solved this problem, by using a PCIE extender cable to allow the GPU to be mounted wherever you like.
