The Best X299 Motherboards for Intel’s Skylake-X, i9 Processors

There has never been a better time to build a high-end gaming desktop. Between AMD’s showstopping 16-core Threadripper CPUs and Intel’s shockingly powerful i9 processors, consumers have a lot to choose from.

Anytime Intel releases a new batch of X-series (previously known as Extreme Edition) processors; they push the boundaries of what’s possible with current technology. These changes aren’t restricted to their new chips; they also need a new motherboard to go with it.

Intel has consistently lead the CPU industry, which means that most consumers on the market for a high-end CPU are eyeing up Intel’s latest processors. But if you want to take advantage of everything these CPUs have to offer, you’ll have to pick up an X299 motherboard. Although these motherboards have a lot in common, there are also a few key differences between them. In this roundup, we’ll be taking a look at the best X299 motherboards on the market. We’ll show you what they have to offer, and help you decide which one is the best fit for your rig.

ASUS Prime X299 Deluxe

Out of all the motherboard manufacturers, ASUS wanted to get the most out of X299. They released a plethora of compatible hardware, with each model supporting a varying amount of the features. Why pick the deluxe over another model? Well, this is the one that has everything. Most consumers who are planning to pick up an i9 chip aren’t willing to make compromises, and this is the board that won’t leave you lagging behind the competition.

Design and Durability

If you want a board that looks as good as it performs, you’ll be happy with the ASUS Prime X299 Deluxe. Featuring aluminum port covers and heatsinks, all of the delicate components of your board are protected from dirt, scratches, and (most importantly) heat. The bolt-on metal look is incredibly aggressive, yet the rainbow silk screening adds a peppy vibe to an otherwise eye-catching motherboard.

Let’s be honest; a motherboard is going to be mounted inside your case. Looks are important, but not nearly as important as durability. Fortunately, all of the most impressive design elements are functional not just in looks, but also for durability.

Take, for example, the stylish plastic ports that everything plugs into. These are made with a unique injection molding technique that encompasses a steel frame. This ensures that your PCIe slots can withstand a lot more force, something that any gamer with a high-end graphics card will appreciate.

Connectivity and Communication

X299 offers a ton of bandwidth for your peripherals, and the ASUS X299 Deluxe makes the most of it. You’re provided with a U.2 port (yes, the “dot” is pronounced. Sorry Bono) which is a significant improvement over M.2. Originally designed for the server market, this port has found itself in enthusiast grade hardware thanks to it’s access to four PCI-Express lanes. You can think of it like SATA on crack, with bandwidth that would make a PCIe SSD cry.

U.2 is still pretty new, so there aren’t a lot of devices that can take advantage of its bandwidth. This is more of a ‘future proofing’ feature, and ASUS still gives you dual M.2 slots, four PCIe x16 slots, and two PCIe 1x slots.

You also have 8 DIMM slots supporting a combined 128 GB of memory. In the USB department, you get three USB-A ports and one USB-C port.

Finally, you’ve got onboard wireless included as well. But this isn’t your typical integrated WiFi. It’s an 802.11ac/ad chipset, supporting the latest technologies. Even if you to buy a modern high-end network card, you likely wouldn’t see much of an improvement in networking speed.

Performance

One of the most common misconceptions is that all X299 motherboards offer comparable performance. If you’re just going to slap your chip in and let it run, then this may be true. However, those of you who like to push the boundaries of your hardware will be glad you chose this motherboard.

This thing is built for overclocking. In the memory department, you can push your chips to 3600 MHz. You may be able to go higher, but the board is rated for this speed. Additional tuning can vary depending on the chip you get. In many cases, it’s all luck of the draw. But ASUS offers you a 5-way optimization system that helps you balance bus speed, multiplier, fan speed, temperature, and CPU utilization to get the best performance possible under all conditions. In combination with the additional cooling we mentioned earlier, this is a board that can be pushed harder than most competing models.

MSI X299 Tomahawk

If you’re looking to get your game on, you need something specifically designed with the needs of gamers in mind. MSI’s Tomahawk motherboard has aggressive performance, and an aggressive look to match. Combined with the fact that it’s a little cheaper than some of the other options on the market, this is the number one choice for many consumers.

MSI accomplishes this through a careful balance of toning and angularity. The steel plate over the aluminum heatsink isn’t exactly high contrast, and yet this is one of the most visually appealing parts of the board.

Impressively, this stunning good look doesn’t come at the expense of durability. The board offers superior cooling performance, and uses metal to reinforce all of the breakable parts of the board. There are a few unique features thrown in as well. Both of the M2 ports are protected with a metal shield, preventing both physical damage as well as RF radiation.

Connectivity and Communication

MSI didn’t skimp on your connectivity options, allowing you to connect all of the hardware you’ve got (both new and old) to the modern PC of your dreams. It supports 128 GB of memory across 8 DIMM slots, four PCIe X16 cards for your ideal Quad-SLI system, and two more PCIe 1x slots for peripherals.

For storage, you’ve got a number of options available. Those of you craving your low-profile SSD fix will want to take advantage of the dual M.2 slots, and if you live on the cutting edge you’ll be able to use the U.2 port. It also has built in support for PCIe NVMe storage, so you can use these compatible devices in whichever slot you choose.

MSI’s Audio Boost system is powered by a Realtek ALC1220 chipset, providing consumers with 7.1 channels of digital audio. This is distributed through one of the two optical audio ports, or through 7 3.5mm analog outputs.

Gamers looking to keep lag down tend to prefer a wired connection, and MSI doesn’t disappoint in this regard. Their Ethernet is powered by an Intel chipset designed primarily for server applications. While it’s overkill for most consumers, gamers will appreciate the improvements in lag and packet loss.

Connectivity and Communication

Despite all of the added durability, this board is still affordably priced. They were able to accomplish this by stripping out ports that most find unnecessary, leaving only the ones you need. Despite this comparatively Spartan design, there is still plenty available. You’ve got one USB 3.1 type A port attached to a four port hub. A separate, dedicated channel feeds a single USB 3.1 type C. You also get a plethora of USB 2.0 ports, and one dedicated charging port that still has power even when the computer is turned off.

This board can support up to 128 GB of memory across 8 DIMM slots, and has the full suite of both analog and digital audio outputs. There is no wireless networking included, but for most gamers using Ethernet this won’t be a big deal.

Performance

At standard clock rates, this board provides no better performance than any other. But where is does stand out is overclocking. Thanks to the beastly coolers found on it, you’ll have lower temperatures and higher overclocks. It’s rated for 3600 MHz memory clocks, but many consumers have been able to push it even higher. If you’re looking to push the limits of your chips and don’t have a water cooling system, this is the next best option.

Part of the reason is the fact that there isn’t much integrated hardware. The lack of a WiFi chipset leaves more room for your north and southbridge to take on the heavy lifting, offloading all the work to your external cards.

Gigabyte X299 AORUS Gaming 9

Although gigabyte is often considered the king of budget motherboards, they still know how to throw down at the high end. The AORUS gaming 9 is their top-tier X299 motherboard, and offers much more than many of the competing models.
