I haven't had any major issues with the graphics on my new MacBook and I don't plan to use it for cutting-edge games. But, I did try playing Wingnuts 2 and noticed a considerable slow-down with a lot of enemies on-screen. I've also noticed some "hangs" in the iTunes visualizer when the song changes.
Hopefully these issues will be resolved with more mature drivers.
