they are both NOT good for gaming, but between the two i would take the A6 3500 because it has 3 cores. Dont be so close-minded, Im sure there are more CPU's to chose from. what are the rest of your system specs? graphics card plays a more important role than cpu, if you have no dedicated graphics card your not going to be playing anything but pre-2003 games. If you can, look at intel cpu's, they make much better cpu's for gaming, even their low end pentium G range is better for gaming that the CPU's you are looking at.
