Summary: AMD has really brought out some players in the lower cost space. The Athlon II X3 415e is a fantastic energy efficient CPU. It’s got a lot of power, while using less than half the power of the regular Athlon IIs. Plus, it’s ability to handle a stable 18% overclock is not something that should be left overlooked. Keep in mind though, if you are looking for a lot of performance on a budget, the Athlon II x3 440 3.0GHz is about $80 and is faster out of the box.
