This is my new gaming rig for next few years (sorry for the ugly power cables to gpu..i´m currently waiting for the Cablemod). Previous computer was powered by i5 6600K (i lost silicon lottery..4,3Ghz was maximum with decent voltage), basic Z170 mobo etc. and wasn´t able to match my 1080Ti in 2560x1440 resolution so i decided to build a pc which will handle at least next 2 generations of high end GPUs.

In the beggining i wanted to make a Ryzen build but their gaming performance is worse than latest Intel architecture so i waited for in that time rumored Coffee Lake and it was worth it.

Storage, graphics card, psu and fans are from previous build.

In the future i want to do custom water cooling loop (probably with GTX 2080Ti or how will be big Volta GPU called) and make smoked tempered glass side panel like Paul´s Hardwares Arctic Panther.

Part Reviews


I´m able to run core at 5,1 Ghz, cache at 4,9 Ghz with 1,36V (delidded) so i´m really happy with this piece of sillicon and it´s total gaming monster.

CPU Cooler

Great cooling performance but the pump is rattling a little bit even in idle at lowest rpm. Edit.: Even second one is rattling and humming really loud (it´s clearly noticable through sounddampened sidepanel of R5) so i don´t reccomend this AIO.

Thermal Compound

Best thermal compound. :) Temps are 5°C lower than with classic thermal compound (arcitc MX4).


Great aestethics, good overclocking features etc. but it´s pricier than rivals from other vendors. I had to return first piece because of really noisy coil whine from VRM, but second piece is without problems.


One of the best memory kits for modern Intel platform.

Video Card

Total beast. Great aestethics, massive and silent cooling system. Only cons is 3x8pin.

Case Fan

Their airflow is good but they´re vibrating little bit in lower rpms.

51 Ghz? Holy cow! (look on the completed build list at yours. Mine says @51.0)

crimsondragon 2 points 3 months ago

Yeah mine says that too... BTW nice build!

Where do you see 51Ghz? :D

Boith 3 Builds 2 points 3 months ago

I bet it's deadly with a 51ghz cpu. Good build btw.

ssjg5rlly -3 points 3 months ago

i bet it's extremely bottlenecked too.,

Absolutely inexcusable! I will never forgive you! You know what, fine. Because I like you, hand over the graphics card and I'll call it even.

Yahtadi 1 point 3 months ago

Yea.. Tag me again when he chang to Cablemod already

Triniking 2 points 3 months ago

Great build.

But I honestly ended up here because under the page for the i7-8700k completed builds it says you got it to 51GHz. gg

How is the Max X Hero, I am looking for a quality well made motherboard?

hanz917 submitter 1 Build 1 point 3 months ago

You can´t make mistake with this mobo but pay attention for VRM coil whine which was in my first piece really loud.

Great pc build

Mrchoclo90 7 Builds 1 point 3 months ago

WoW, very good PC, the 8700k is an incredible processor for the domestic range and the MSI Lightning is a great GPU (I would have liked some detail in yellow as the previous Lightning) and other low price is not it?

Anyway, congratulations for your PC is an incredible =D

hanz917 submitter 1 Build 2 points 3 months ago

Thank you man! I actually liked yellow color scheme on the Lightning series more than this black/silver but it´s still one of the best models of GTX 1080Ti.

Stereotypical_Whale 1 point 3 months ago

jesus! 6 cores with hyperthreading at 5.1?

hanz917 submitter 1 Build 1 point 3 months ago

Yep. It´s reaaly fast. But thats stable frequency for daily use ..limit of my silicon is even further (around 5,4-5,5Ghz) but thats a work for undercooled water. :D

Stereotypical_Whale 1 point 3 months ago

You can't even touch me tho, i got my pentium g3258 at 4.4ghz stable!!!!!!!!! That's extreme sh** bro

CSGOmustang 1 point 3 months ago

So custom water cooling gets you considerably better temps than AIO? I’m looking to overclock my 8700k as high as possible while stable. I am debating between custom soft tube water cooling for cpu and gpu but some say it’s the same as AIO.!8 just don’t know. Awesome build!!!! I love it. Looking to build something very similar. Pre ordered my 8700k. Just need to order other parts. You know anything about memory? Is a lower speed ram with low latency better than a higher speed ram with higher latency. So confused. The higher the speed, the higher the latency. Thanks.

51 ghz oki

hanz917 submitter 1 Build 1 point 3 months ago

Guys where do you see 51Ghz? :DD

StealthDestro121 1 point 3 months ago

On the completed builds list.

Yahtadi 1 point 3 months ago

It says 5.1. Why do people keep saying 51Ghz?! I curious as well

StealthDestro121 2 points 3 months ago

On this page it says 5.1. On the completed build list page, it says 51 Ghz.

holy shet

kingawsume 1 point 3 months ago

How's the airflow in that Blackout? Is the front panel mesh or something?
