Hi lately i noticed i have cpu bottleneck in competitive FPS games i play. Especially quake champions, because there isnt vulkan or dx12 support. i have a fairly good ,but old build:

asus z97-k
i7 4790 ( non-k)
asus 1080ti
16gb ram
fsp hydro g 750
144hz acer predator gsync ips

what im thinking: sell my 4790, buy a 4790K used, put it in and bumm i have around 400-700Mhz gain for around 50-60$

two questions:
1: will a 4790K run on tolerable temps under a Scythe Mugen MAx air cooler?( 4790 4ghz had 62as MAX temp when gaming.)
2: is the 400-700Mhz gain sufficient? How much performance increase can i look for in game? Currently i'm around 90-110 fps with crazy cpu bottleneck( cpu at 100%, gpu around 60-70% )

If you can sell your i7 and buy the K model for a fair price without having to invest much money, then it will definitely help but don't expect miracles or zero bottleneck with the 1080ti. You are looking for a 10% performance boost when overclocking cpus, which is not bad but not great either.

Keep in mind that shooters are usually benefited from fast ram. 2200 mhz and above looks like to work better for many fps games
Your cooler looks like a big high performance budget piece with 6 heat pipes. Usually they can deal with the high thermals of a multithreaded i7 but don't quote me on that. You ll have to test it yourself and see how it goes.

so you say the 600-700mhz boost will get me around 10% in raw performance numbers? and yeah it wouldnt cost much tbh, aruond 50-80$ in total( including the thermal paste and fuel cost lol )

More or less yes. It's better than nothing. Since upgrading the whole platform would cost a lot money, you may give some life to your system with such a low investment. I did a similar thing with my system, i had to swap my old H61 motherboard for a Z77 model to overclock my i7 3770. I jumped from 3.7 ghz to 4.4 ghz and the results were impressive for some titles.
