For comparison sake It will be equivalent of streaming netflix and you can customize how much geforce uses as bandwidth. I think for full HD the recommendation is 25+ Mbps. The difference is that you can set everything to full detail since it will be rendered server side, it will be video after all. There is a free tier so you can try by yourself on a laptop. If you want to check the web browser version, you just have to switch the browsers user-agent to simulate chrome OS and you'll be good to go. I did and I'm able to run any supported steam game in full details on a crappy 7 year old laptop with 1gb video card under ubuntu.Yeah I'm sure everyone who has slow to barely decent internet speed it will run beautifully!!!
