Actually a lot of such ideas in the market. I recently read about some cloud gaming service where you can play your games in the cloud.
So dont need to require expensive high performance gaming PC, just play from normal PC while the game runs in the cloud. Of course this requires a very fast fibre connection and servers close to home to reduce latency but with 1 or even 2Gbps fibre here, it should not be a major problem. Of course, the service is not free and its chargeable but it saves you the cost from regularly upgrading your PC parts to play the latest games. This technology is still quite new so can expect it to be buggy but I can see the potential.
I wont post the name here, in case its against the rules but its listed under this wiki.
