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 Intel Core i3-4340 is a budget dual-core four threaded 4th generation Haswell processor released in Q3 2013. At the time of release it was the top end Haswell Core i3 chip – offering great value for money, performance and power efficiency. It scores a strong effective speed of 89% with its base clock of 3.6 GHz which means that users will experience smooth and fast performance with the majority of desktop applications. Its two cores and four virtual cores are adequate for most games. The i3-4340 features Intel HD Graphics 4600 which are probably okay for playing some older games in 720p and are comparable AMD integrated graphics (for example, on the AMD A10-5800k) when it comes to 3D gaming. But serious gamers will need to have enough money left over after purchasing the i3-4340 to spend on a stand alone GPU. [Nov '14 CPUPro]
