5.8 Out of 10

The Intel Core i7 3930K is a powerhouse of a processor that is up there, on par with one of the best processors in the Sandy Bridge series- the i7-3960X. The 3930K may not have all the characteristics of the 3960X, but what makes it a satisfaction to all, but the most die-hard fans of the Sandy Bridge series, is its price which is almost half than the price of the 3960X. The differences between the two processors is minimal, with the 3930K clocking at 3.2GHz, instead of at 3.3GHz; and a cache of 12MB instead of the 15MB of the faster chip. But that’s the biggest differences between the two, which means the 3930K will be able to fulfill any task you give it, and still have leftover processing power.
