If you are simply relying on integrated graphics, then the A8-3530m's IGP would be better than Intel's HD 4000 IGP.
Does that mean the A8-3530m is good for games? Depends on how high or low your expectations are. Integrated graphics are still weak compared to discrete graphic cards.
Fixed it for ya. Also, the A8 can do Crossfire with some discrete Radeon cards, so it can be used to increase the speed of a discrete crd, making it useful even with a discrete card whereas the HD 4000 IGP can't work in unison with a discrete card, it can just disable itself to save power.
