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 FX 6-Core, like most CPUs from AMD, delivers reasonably good server orientated multi threaded performance and consequently good processing thoughput at a reasonable price tag. Where the FX 6-Core lacks is in the area of single core performance which although not normally a major problem for server workloads, is always very relevant to desktop users. The overall performance of the FX 6-Core is comparable to Intel's five years younger Core i7-950. There are server orientated use cases where the FX 6-Core will excel thanks to its excellent overall throughput and in those instances the FX 6-Core represents good value for money. But typical desktop users will find far better value elsewhere[Sep '13 CPUPro]
