Sure can. Most games tend to lean on the GPU more than the CPU. However there are some games that CPU dependent. Here's some off the top of my head that require a decent CPU: WatchDogs, BF4, Civ5, Star Citizen, and Skyrim. Which A10 do you have? An AMD 83xx or an Intel i5 may be a significant upgrade for a APU.
