The sooner, the better for this heavy Chrome tab user.
Why are consumers stupid enough to use Chrome? It is a well known CPU and RAM resource hog BECAUSE it is spyware for Google. Why do you think Chrome is eating up so many CPU cycles? Its sending info about you and your browser activity & clicks to Google!
Only use open source browsers like Firefox!
