Does power efficiency matter for GPUs?
Where does power efficiency rank when buying a GPU?

When you see people comparing GPUs, things like FPS per watt aren't usually at the top. Users like to see how much performance they're getting for the price. Getting a more power-efficient GPU is always a bonus, but it's rarely a deal-breaker for gamers or enthusiasts. If you're a laptop user, however, things can look pretty different pretty fast. The same is the case with HTPC users or those running a workstation, where power bills might be a bigger concern.
