I'm looking into a new notebook and it seems I'm reading that the core i7 processors don't support switchable graphics (nVidia Optimus). Is this true? I can't find a straight answer anywhere. And does Optimus make much of a difference in the battery life in the first place? The problem is I want to be able to do some gaming, but if the battery life difference is large enough, I would consider grabbing an i5 with Optimus instead. I know the i5 processor is more than enough for gaming, but then I end up with a lower end video card, like the 420M, which isn't too great of a notebook gaming GPU.
Thanks.
Thanks.
