AMD Athlon II is a cheap overclocking CPU that really isn't worth it at stock, the real gem of this CPU is the ability to overclock.

When we overclock the CPU to 3.9 GHz, it is able to beat the stock Phenom II results quite impressively as well as the Phenom II's overclocked results, which we only managed 3.6 GHz.
