The Intel i7-8700k was launched quietly on October 5, 2017, and the rest, as they say, is history. Made as an answer to AMD’s Ryzen processors that were threatening to knock Intel off the CPU leaderboard, the i7-8700k has firmly put Intel back in the driver’s seat. Intel codenamed this 8th generation CPU the Coffee Lake, which I think is just a way to lull the competition into thinking it performs like a laid-back vacationer enjoying coffee by the lake watching the sunrise. However, there is nothing lazy about this CPU. With its 6 cores and 12 threads, it is a powerful and fast beast that has left its competition choking on its fumes.

The only problem is (there’s always a catch, right?) the Coffee Lake works best with motherboards that house the newer 300 series chipsets.
“Pshaw!” You say, “who cares about the motherboard?”. Truth be told, you should! Pairing the i7-8700K with an inferior motherboard would be like buying an Audi R8 and then swapping out its engine with a Ford Fiesta. The car will still run fine, just not as well as it could. Pairing it with the right motherboard will allow you to get the most out of the Intel i7-8700K processor. Trust me, it could be the difference between you being pwned (for all the non-gamers out there, that means losing badly) or not.
There are a plethora of motherboards out there that are compatible with the i7-8700k. Here are our picks for the 5 best ones.

FAQ

What is the difference between gaming and a PC motherboard?

Simply put, a lot! Gaming demands more performance that pushes the limits of the CPU, while a regular user will be satisfied with a lot less. For gamers, it is all about the experience. Having a motherboard that delivers higher frame rates could be the difference between a high-class experience and an irritating jerky one. Motherboards built for gaming also use high-quality materials throughout their design. An example of this is the gaming motherboard sockets which use anywhere between 10 to 15-micron gold plating while normal PC motherboards can make do with 2 to 4-micron. These reinforcements ensure improved performances, especially for overclocking.

How much Random-Access Memory (RAM) does my motherboard need for gaming?

Normal motherboards that run office PCs come equipped with 4 GB RAM, which may have been enough 10 years ago to have satisfactory gaming experience. With today’s games being heavy on the graphics that give users studio-quality audio and visual details, a minimum of 8 GB is required. The optimum RAM for gaming is 16 GB which will be sufficient for all the demanding game titles out there today and then some. If you are on a budget, buy a motherboard that supports 8 GB RAM but has extra memory slots that can be used for future upgrades.

Is inbuilt wi-fi a must-have for a motherboard?

No, inbuilt Wi-Fi is not a must-have feature for a motherboard. All boards come with PCIe slots to which you can easily attach a PCIe wireless network card. The motherboards that do come with inbuilt Wi-Fi just have a bundled Wi-Fi card already inserted into one of the PCIe slots with connected antennas. For sure, this feature is convenient since you need not purchase additional paraphernalia, but motherboards with inbuilt Wi-Fi are typically costlier than the ones without. Of course, this point is redundant to gamers, who prefer the superior quality and stability of wired Ethernet connections to Wi-Fi.

Can I overclock the i7-8700k and how do I do it?

Overclocking means to run the CPU at speeds higher than the factory set speed. A lot of processors come with locked multipliers that block users from tinkering with them. All Intel CPUs with a ‘K’ in their name come unlocked and therefore can be overclocked. So yes, the i7-8700K can be overclocked.

The Coffee Lake CPU comes set at the default speed of 3.7 GHz. Overclocking it entails accessing the motherboards BIOS that boots up the system and increasing the clock rate or the voltage or both. In times past, this used to be an arduous task where the speeds and voltages had to be increased bit by bit, followed by rigorous testing to see if the system stayed stable. Not anymore though. The i7-8700k comes with an inbuilt multiplier that can make you a master overclocker in a matter of minutes.

Conclusion

To conclude, the i7-8700k is a great processor built for gaming, and it deserves to be paired with a motherboard that can get the most out of it. All the motherboards reviewed in this list have a proven track record of doing just that. I hope it has made the task of choosing the one that fits your unique needs a much simpler one.
