At least in Europe the market is shifting to a more "green" awareness. Getting most performance at the lowest possible energy cost does matter, because energy is expensive in western Europe. Lower voltaging will give you the same performance compared to the standard setting but shave off some bucks from your energy bill. With the Core i5/i7 series, you need to disable Turbo, of course Turbo will increase power consumption. We did not only lower the VCore to 0.975V, we also reduced the VTT to 0.965V. And can you believe it, the result was amazing. Again we checked the result with Prime 95, this time over night to make sure it works flawless.
