yeah that might happen

I mean for gaming there is already the Ryzan Max+395 which already is beyond the level of low end graphics (at least if placed in a desktop where it's not heat/power throttled). But it's a bit of a unicorn (especially if you look for a system where it can run full throttle).

but I'm not sure about the beat nVidea part, nVidea has some experience with putting ARM CPUs on their graphic cards and as far as I remember on for their server center solutions there is one which pairs up graphic cards (and their RAM) over PCIe and mostly cuts out the CPU
