There is little headroom on increased speed and the price to get there is higher than previous generations. If you aren’t planning using Windows 10 – Kaby Lake will not support previous versions of Windows natively (There may be work arounds but…) It’s worth noting, this version does not come with a Stock Fan, so you will need to buy a 3rd party CPU Cooler for it.

Getting to 5.1Ghz
I updated my ASUS BIOS to the newest version
I used the ASUS Windows app AI Suite 3 to stress test the system to its Max stable performance. It actually did a very good job. I rebooted Windows, (hiit F1) entered the BIOS and saved the OC settings into the ASUS BIOS Profile. This saved a lot of time doing manual settings in the BIOS first, then running stress tests.
My Temps Idle speed 28-30C – Under Load 70c-73c
Kaby Lake CPU’s run warmer under load – but should Never exceed meet 80c Max temps.
I never run my older Intel CPU’s beyond 60c as stability couldn’t be insured. All my OC’d PC’s are still running 9 years later. With that said, Kaby Lake CPU’s run warmer. I have not experienced instability under Max load with the i7-7700K.
The i7-7700K can be overclocked to a stable 5.1GHz with water cooling
You need to run Windows 10. Although some online forums offer work arounds to this limitation. Is it worth it to run into issues down the line.
The speed performance premium may be too high for some.
Consider that I still run two i7 2600k systems I built in 2011 (running at 4.8Ghz) on Air Cooling, The stock speed of a i7 2600k is 3.4GHz – The i7-7700K runs at 4.2GHz and requires water cooling to get to 5.1GHz. The headroom for increased speed considerably less then it was six years ago.
If you’ve purchased or built a high end PC in the last two years for gaming, there may not be a lot on offer here. A GPU upgrade may deliver more tangible speed results.
If you use applications that are CPU dependent 3D rendering or Video editing, this increase in speed is welcome.
For gaming, nVidia/AMD GPU’s play a bigger role on your gaming than CPU’s once did. If you are buying this for gaming, there are cheaper alternatives. I’ve been running this for 3 days without issues. Games: Doom, Battlefield 1, Battlefield 4, Overwatch ran smoothly, without issues – The water cooling fans kicking in consistently.

– This processor is fast. I’ve had a 4770K and it would only go up to 4.1 GHz. Anything above that and it would crash. This processor is overclocked to 5 GHz and I can tell in all my games that they were smoother. Frametimes were noticeably better than what my 4770K gave me.
– Glad that they stopped putting the stock cooler with this CPU. You need a great CPU cooler if you’re going to buy a CPU of this caliber anyway. You need to be able to keep it cool so that it won’t throttle.
– TIM used was crap. I had to delid this CPU and put liquid metal to drop temps. They could have soldered this chip for better temps, but no. Intel could have really done better with this one, but they decided not to.
