Would a Dyson sphere be useful as a means of power generation?

I have heard people (quite possibly on this site) say that by the time a civilization is able to make Dyson sphere it will be useless to build one for power and energy needs. So, would a civilization which can easily make a Dyson sphere make one for energy production, or would they have already have moved onto more efficient means?

Edit: by Dyson sphere I also meant Dyson swarm, or any other thing which encapsulates the sun to harvest it's radiation energy. Also, even through the question is similar to the one suggested as a duplicate the answers I am receiving are quite different.
