as soon as someone puts 16GB of VRAM next to an SoC (Nvidia, soon), the gaming pc is dead. These hot 'n slow discrete components are fun to decorate with RGB but they're yesterday for _all_ segments.
The point is that the dGPU will _become_ the PC, and it essentially has been the PC for a while now, as you are essentially proving with your cybperpunk comment.
Nvidia is preparing to SoC-up it's RTX cards with ARM cores and then it's toast for your rig.
