I use GeForce Now. It fits my needs and the games I like to play. Why pay for my own gaming rig when I can rent it and let others cover the upgrading cost?

There are a few services that allow you to play with the actual game being rendered on remote computers, while your pc only shows the image and sends the input commands. I think the more popular ones are xcloud and geforce now. There are also a few smaller services that allow you to run anything you'd like, without limitations.

I use Shadow, you literally get a high-end PC you stream to any device in real time and can do whatever you want with. Other cloud gaming services only streams the games, so you can't use mods, emulators, etc. Currently playing Avatar: Frontiers of Pandora on max settings, and it's buttery smooth. I also use it for anything else that my laptop can't handle like image and video editing, 3d modelling and rendering.
