I have i7 with the HD4000 + 660gtx combo on my laptop. It's great for accelerating web pages(especially flash) and that's where it ends. But I was fortunate enough to be able to switch to the 660gtx when I need it. I tried gaming on the HD4k for giggles and it was hopeless. The difference in battery makes the hd4k worth it on laptop though. Although AMD's trinity does better. Web browsing with HD4k gets me 4-5 hours. The same tasks with 660gtx gets me 2.5 hrs. With gaming, the difference was only about 15 mins. I would've bought the AMD A10 but those laptops never come with SSD and backlit keyboards.
