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 3950X is the 16 core, 32 thread Ryzen 3 flagship. Although this CPU offers server levels of multi-core encoding performance, there are relatively few, if any, consumer use cases for the 3950X. Streamers are better off using dedicated hardware such as NVENC which encodes far more efficiently than any CPU. Gamers are better served by low latency gaming CPUs such as the 9600K for a fraction of the price. For example, comparing these two PCs shows that the 3950X build offers less than half the gaming performance. The only rational reason to put a 3950X in a gaming build is in exchange for sponsorship money. [Feb '21 CPUPro]
