The main issue I see there is the power still has to come from somewhere. All this would likely do is move the pci-e power plugs to the motherboard and cause lots of confusion related to: “this GPU only requires two plugs of power, but the motherboard has three plugs, do I need to plug in all three? My PSU only has two pci-plugs.”
I know it’s super challenging to isolate power on a board. But I would love for them to add the ability to run any card entirely from the board.
