The CPU is three generations old. The GPU is low end for a gaming system. For games that are two generations old it will do fairly well. For current and future gen games, not so much. You might, probably, make medium settings in many titles but for very demanding titles like Witcher 3, GTA V, or upcoming titles like Doom, Fallout 4 and whatever else comes out going forward, you're going to see a significant lack of the necessary resources.
