That is one game, that isn't such a high GPU intensive one.

This is on medium settings, and though 720p does well the difference between medium and high is worthwhile to people, including me. Also - I am also sure they do not have AA enabled, which makes FPS look much better then it is when compared to graphics card tests that are conducted (FPS wise). This makes graphics cards have a far better visual experience over that what and APU can achieve, but also price is expectedly more.
