If you are going for gaming, something with an i5 or i7 CPU would be better, the intel CPUs will get you higher frame-rates unless the video card is maxed out in both cases. You'll be paying more or the laptop though.
If you will be playing on the LCD screen on the laptop you listed, you should be OK with the AMD chip though, that's a pretty low resolution for modern games.
