I want Google Stadia.
My internet bandwidth is more than enough for 4k 60 FPS and price for their service is pretty good - better than $3k PC for 5 years - you need to upgrade GPU at least every 3 years and CPU every 2 years (and, therefore, motherboard) to keep "high-end PC" title and play new games on "ultra" settings. Here they promise the same for a price, comparable to what my high-end PC takes for electricity.
