Discreet AND Integrated Graphics card?

I have a Lenovo G505s, and it has both a discreet and a integrated graphics card. The discreet is AMD Radeon HD 8650G which should be pretty good or at least decent with modern gaming. However, I feel as though any game I play: Battlefield, Diablo 3, common flash games; they do not have enough FPS even though I lower the graphics settings.

Is there a way to know if my discreet graphics card is doing most of the work? Because it seems like it's not. Or is there a way to turn off the integrated graphics card? So far the device manager says the CPU and the integrated card are one in the same.

Lenovo Yoga 2 Pro vs Apple MacBook Air?

I'm stuck between these two ultrabooks. Both will have an i7 Haswell Processor, 8 GB of RAM, and 256 GB of memory. Now, I will be using this notebook/ultrabook near daily for school. It obviously has to be sturdy and light, which I know they are. But, I will also be doing light video and music editing and some light gaming ( Like Counter Strike: Global Offensive and Civilization V ). Which would be better for me? Both seem like excellent machines.
