The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 CPUPro]

The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. When it launched in Q2 of 2009, it was AMD’s fastest CPU. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. The 955’s effective speed of 63 isn’t impressive by today’s standards, but when coupled with a decent graphics card, it won't cause major bottlenecks for most games. The 955 was pitched against the high-end of Intel’s Core 2 quads, and now costs a fraction of its original list price as one would expect, however there are better alternatives on the market now. [Dec '14 CPUPro]
