You will want to make sure it has 2 sticks of RAM and not just one. Two sticks of RAM (preferably same size and speed i.e. 4GB DDR3 1600) will optimize the performance of the integrated GPU.
I have the slightly faster A10-4600m with 7660G and it can manage single player BF3 just fine but multiplayer good luck, I haven't had much. Low settings 1024x600 it struggles quite a bit even. BF3 is a very CPU *and* GPU heavy program and this single CPU is trying to do the job of both. Otherwise it does manage other games just fine including Far Cry 3 at low settings, and you can overclock the GPU a little bit (about 1000MHz compared with 685MHz stock) and helps adding a few FPS.
