The third gen Ivy Bridge Core i7-3770K can't really be described as a consumer orientated processor. With 8 threads and four cores its capabilities are better aligned to server use. For price insensitive consumers that want the best of the best, this is currently one of the fastest processors available. The PassMark Single Thread score of 2080 points puts the 3770K right at the top of the pack in terms of raw processing power and real world performance. The GeekBench and PassMark scores of 17210 and 9653 are within 20% or so of the best we have ever seen. Despite the near record breaking processing throughputs the 3770K is only rated at 77 TDP, which is very low by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]

The Core i7-4960X is Intel's top of the range desktop processor which sports six physical and twelve hyper-threaded cores. The 4960X was released in 2013 but it uses an FCLGA2011 socket which is supported only by the X79 chipset and is now three years old. As a result an investment in this processor forgoes the last three years worth of platform advances which include, amongst other things, on-board USB 3.0 and additional SATA 600 MB/s ports. Comparing the 4960X and the 4930K shows that when overclocked, the 4930K is able to best the extreme 4960X at nearly half the price! Finally comparing the latest Haswell 4770K to the 4960X shows that 4770K is again able to best the 4960X, this time at a small fraction of the price. The 4960X is significantly overpriced and there is far better value available elsewhere. [Mar '14 CPUPro]
