False. There is a slight difference in FPS. Slight is different from NONE. The sweetest spot for a gamer is 1600. Although its a different story when you're using an APU and clearly not the case here. 8GB is enough but games nowadays consumes more than that with OS and other running applications.
@TS, IMO, if you have the money to blow, take the 16GB 2133. There is only a slight difference in price. In terms of real world performance, what you'll feel much is the 8gb vs the 16gb and less with the 1600 vs 2133. But still, there's a difference.
