Up until now, Aorus was reserved as a separate entity under Gigabyte, responsible for gaming laptops. However, Aorus has now jumped in on the ever-changing and dynamic gaming wagon, expanding its horizons from just gaming laptops. Aorus’s innovation and passion for the gaming industry have produced the GA-Z270X-Gaming 7 motherboard which has made it to our list thanks to its unique blend of excellent power delivery and smart features such as the implementation of Thunderbolt 3.

Moving in for a closer look at this board, there are 4x DDR4 dual-channel memory slots that can give up to 4133MHz (OC). There is support for ECC  memory as well which allows for detection and correction of common kinds of internal memory hindrances.

The reinforcing of the PCI-E Express, memory slots, and the added subtleties for ease in diagnostics are bonus points. The Z270X uses the much-approved standardized 8+3 (8 for core and 3 for GPU) phase design for power. Dual heatsinks connected with a copper pipe cover the MOSFETs. Just beside the SATA ports is another solid heatsink responsible for cooling.

The operational amplifier used offers an impressive 120dB SNR. In the back, I/O connectors, Aorus, along with the standard USB and audio jacks, provide 2 USB 3.1 ports as well. The RGB on the board is smartly implemented and can be controlled using Gigabyte’s RGB Fusion software.

Gigabyte’s BIOS ends up supplying more voltage to the Vcore than what is required resulting in a 94 Celsius temperature. This will cause throttling and, as a result, give reduced clock rates. This setback can be resolved manually however, with a price and brand like this, you’d expect Gigabyte to not have had it slid by under their noses.

If you are interested in Gigabyte’s somewhat better offerings, check out our review of the Gigabyte Z390 AORUS Pro WiFi which is a fantastic Z390 motherboard that should be on your upgrade list.

Resolve the temperature control manually and you have a solid, sturdy, and well-structured board to work with. Gigabyte, with easy OC, follows that here too giving the users pre-defined as well as custom settings to work with. For what the Z270X offers, Gigabyte is quite generous with its price tag as well. This motherboard is a worthy one and arguably the best i7 6700k motherboard when it comes to overclocking. Aorus has definitely proven itself to be a worthy competitor in the motherboard market.

Asus has made some changes and taken a step back from the exquisite design of their ROG series. The Z170 may not possess the flashy over-the-top mechanics that ASUS have taken with their ROG Maximus, but this motherboard has still made it to our list as number 3 for good reason.

Asus is consistent with one thing in their boards, maximizing functionality and inoperability of their motherboards in terms of memory. Regardless of this being an entry-level motherboard aimed at the mainstream gaming community, their philosophy holds here as well. You can be sure that this motherboard will hold to its claim and be functional with every type of memory that you decide to go for.

The Z170’s 4x DIMM slots are capable of supporting a maximum of 64Gigabits of DDR4 RAM allowing up to 3466 MHz speed. The 10+1 digital phase VRM is responsible for the processor and the integrated GPU. Also, a key bonus is the addition of a couple of extra PCI-E 3.0 ports allowing the users to tap into Quad-SLI and Quad CrossFireX Technologies. You should also brush up on the differences between SLI and Crossfire if you are interested in these technologies. On the networking side, Asus’s ROG GameFirst III will allow you to tune up corresponding to whatever network-oriented task you have to do.

While the Z170 Pro Gaming offers the excellent sweet spot between performance and price, the aesthetics of the board itself is a very risk-free, tried, and tested design in the “do it yourself” dominion. It is relatively satisfying since the black color works well with almost all designs, however; the board lacks the flexibility and controls the RGB lighting offers.

Another feature- or lack of feature- that stands out is the omission of metallic reinforcing plates on RAM slots and the PCIe ports. The heatsinks are constructed using the push-up ideology, unlike the screwed-in structure as you’d find in Asus’s ROG line. Speaking of the lack of features, this board also has no WiFi built-in, although that can be solved using an aftermarket PCIe WiFi card.

The Asus Z170 Pro Gaming works well to serve the new builders as well as the seasonal PC enthusiasts. The architecture of this motherboard is robust and a joy to look at. The construction of this version of the motherboard was intended towards the more average gaming population but overclocking with this is still a cinch and can be done with a touch of a button. All these coupled with its very moderate price make it a phenomenal choice for all tiers of builders.

While the top 3 spots of this list have been taken over by the more high-end and pricy motherboards, it seems as any compilation addressed towards the gamers is incomplete unless the needs of the ones sitting in the middle are talked about. The MSI Z170A Krait Gaming is there to pat the backs of all those who want the sweet gaming nectar but are not looking for the enthusiastic, OC-driven experience. The Z170A Krait is aimed at entry-level gaming in 2021 so let’s take a look at what MSI has to offer for its 30th anniversary.

The new lineup of MSI boards has now unlocked Military Class 5. What that basically means is that the new boards, including the Z170A Krait Gaming, can now withstand 5 times more temperature rises, and the working longevity of the components has been drastically improved. Apart from this, this board features dual-channel 4 DIMM DDR4 slots allowing up to 3600MHz. The placement of the M.2 port is one to be praised because its strategic placing makes it benefit greatly from the airflow of the CPU fan.

MSI’s magnanimity put in 2 USB 3.1, 2 USB 3.0, and 4 USB 2.0 and 2 CPU fan headers which will come in handy when using a standard heat sink or a liquid cooler. The two heatsinks perpendicular to each other cover the MOSFETs, however, are not connected in any way. The spotlight of the design, however, is taken by the large heatsink covering the Z170 chip with exceptional finishing.

For their audio, Krait uses Audio Boost 3 combined with OPA1652 operational amplifiers. These paired with the Nahimic Audio enhancer, and isolated audio solders work together to deliver a more than decent SNR and onboard audio. Using the 8 phase VRM configuration, the Z170A packs quite a hefty punch with its low-price tag which can’t be said for the competing ASUS motherboards, giving further fuel to the ASUS vs MSI debate.

What went through the minds of the engineers when designing the placings of the SATA ports is a mystery. The ports are facing outwards which is confusing- to say the least, in terms of cable management. As a result, unless your cable management capabilities are perfect, you may not be able to install a second GPU. Sure, this is not a modern motherboard with flashy features such as PCIe 4.0 support, but such fine details do still matter when it comes to convenience and usability.

Krait decided to cut the extra over-the-top features with this model however they still have succeeded in delivering a terrific board with a very friendly tag on its price. The Z170A is an excellent entry priced board perfect for gaming which was very well what Krait was aiming for. This is a must-buy for those who are looking to enjoy the top-notch features without spending too much cash and burning a hole in their pockets. Its solid, well-thought design along with its simple yet somehow unique black and white design has attracted many a gamer. All of this makes this board a strong contender when it comes to the title of the best i7 6700k motherboard in the budget category.
