The first thing you need to realize going in is that gaming laptops aren't your everyday laptop. Yes, they are more than capable of running all of the tasks that you would do on a typical business laptop, but the addition of a high-end graphics card invariably means that battery life will be a secondary consideration. Alienware has shown that there are ways to get around this, and hopefully we will see more of that in the future, but the Alienware m15x still depends on brute force in a sense to provide long battery life. You might think offhand that achieving over four hours of battery life is a real accomplishment, but two batteries providing 97 Whr of total power isn't quite the same as being energy efficient. The ability to shut off the discrete GPU on the other hand is something we should have seen years ago. What we really need now is that same functionality for SLI notebooks.
