With that said, I think the new hangouts has a lot of potential. One thing that really annoyed me with the old hangout was that you couldn’t start one without it starting you webcam right away.

Safari itself doesn’t use that much CPU while in the background, probably beteen 0.5-1%. However, the web-content, like images, gifs, flash-videos all still use CPU when you have another app selected, easily above 10%, even 20% of CPU power.
