This is an expensive CPU. I returned it and purchased the Core i7-4930k instead.

Summary: This one is difficult to rate because I returned it without breaking the seal on the box. Soon after I ordered this CPU, I read some reviews that indicated that the CPU that is one step down from this, the Core i7-4930k - 3.4 GHz, was probably a better choice. I returned the 4960 and ordered a 4930.
Summary: I was very excited about my new computer. i was near completely builded. I ordered the Intel 4960x, however seller shipped me a wrong item. I never got to use my new processor. instead, i went to microcenter purchased a 3960x instead. since it was on sale for $700.00.
Summary: This not a review, more of a question and more aimed at the person who put the description up/on Amazon. Advertised is an "Intel Core i7 4960K Extreme". There is no "Intel Core i7 4960k Extreme". There is, however an Intel Core i7 4960X. There is only 3 i7-4**** in existence at the moment.
