The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]

The FX-8370 is a top of the range black edition Vishera eight core processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is both cheaper and faster than the FX-8350. The FX range offers high performance and this particular processor holds a world record for reaching an incredible 8.7 GHz when overclocked under lab conditions. For typical users however, the FX-8370 runs at 4.0/4.3 GHz (base/turbo) and typically hits 5.0 GHz when overclocked. Its effective speed is 83 which is currently only exceeded by AMD's 20% more expensive FX-9590 (scoring 85), making it relatively good value for money. Eight cores aren’t necessary for most applications, but things are changing and if you heavily rely on multi-threaded applications then the FX-8370 may be a good choice. [Dec '14 CPUPro]
