Aw: i7 4790k vs i7 39/49/5930k ? :)

Hi and a warm welcome to our forums Marijan!
The article you suggested is already planned
In general the findings of our CPU gaming performance articles are always the following way: Since we max out details, the VGA becomes the bottleneck in a gaming system. In this case the CPU only plays a secondary role not being able to push frame rates by more than 5 to max 10%. If you'd be testing a setup with a low resolution, such as 720p and low details you'd see that performance scales with the CPU. In this case the VGA isn't the bottleneck anymore, now the CPU is the limiting factor.
In the real world the latter example doesn't make sense. If somebody plays games on a computer, then that person is automatically going to max out the settings to a point where the system can run it smoothly. In the case of a "normal" PC frame rates will then be somewhere in the range of 30 to 120fps. To put things in a very general way: when frame rates are in this range the VGA is bottlenecking performance, again meaning the CPU has no major influence on performance.
Today's games are able to handle four cores in an efficient way. Regarding the two CPUs you mentioned: the 4790K supports Hyper Threading and therefore there are eight virtual cores available to the operating system. Applications/games, that support up to eight or more cores scale rather well with CPUs that support HT. Apart from that there is absolutely no game, which benefits from more than eight cores. Which in the end leaves the conclusion that today a Core i7-4790K is more than enough for gaming.
The bottom line usually also goes like this: if you want to build a punchy gaming PC and your budget isn't unlimited then you better save a few bucks on the CPU and spend that money on a more powerful GPU.
I hope this answer was helpful. Keep hitting us with questions if you have more
