Motherboards
The cats are out of the bag, and everyone and the dog knows that new Intel and AMD CPUs and chipsets are coming along in relatively short order. As we've already discussed, we don't think you should buy a motherboard right now. Should you have an immediate need for an upgrade or a new build, here are our picks.

Buying a motherboard these days is pretty straightforward. There are only four major manufacturers to choose from, and their offerings have very similar performance and peripheral connectivity at each price point. The main differences between competing boards lie with their Windows software, firmware, and overclocking tools.

  • Asus is the biggest of the four main motherboard makers. We think Asus boards have better Windows software and firmware than the competition, plus the most intelligent and reliable auto-overclocking functionality. The company's firmware interface offers the best fan speed controls around, too. Some Asus motherboards ship with cushioned I/O shields and header adapters that make it much easier to connect finicky front-panel headers. Overall, an Asus board should offer the most polished experience of the lot.
  • Gigabyte's 100-series motherboards are also a good choice, even if their auto-overclocking intelligence, firmware, and Windows software aren't quite up to par with Asus'. The company's firmware fan controls can be quite dated, but Gigabyte's latest Windows software largely makes up for that deficit, and the company's latest round of firmware has been better on this point. Some Gigabyte motherboards ship with cushioned I/O shields and header adapters, too. The inclusion of Intel Alpine Ridge USB 3.1 and Thunderbolt controllers on many Gigabyte boards is also a big plus for this generation.
  • MSI's motherboards are solid, as are the company's firmware and software. The nicely-retooled fan controls in the firm's 9-series firmware have been carried over to its 100-series boards, though the company's auto-overclocking intelligence remains fairly conservative and somewhat rudimentary.
  • ASRock generally aims its products at more value-conscious buyers. ASRock boards typically offer a great hardware spec for the money. In our experience, however, ASRock's firmware and Windows software leave much to be desired. ASRock boards are appealing primarily for their budget price tags.

Budget

Product Price Notable needs
Gigabyte GA-H170M-D3H $89.99 Intel LGA1151 processor

Gigabyte's GA-H170-D3H is an interesting choice for non-overclocked Skylake builds. Despite its smaller size, it still offers an M.2 slot, an honest-to-goodness Intel Ethernet adapter, and a full complement of six SATA ports. There are also two PCIe x16 slots with CrossFire support, too. If you don't plan to overclock, and you're OK living with DDR4-2133 RAM only, the H170M-D3H seems like all the motherboard one would need for a budget system.

Sweet spot

Gigabyte GA-Z170-HD3 $114.99 Intel LGA1151 processor, ATX case
Gigabyte GA-Z170X-UD3 $144.99
Gigabyte Z170X-Ultra Gaming $169.99

For folks who want a basic Z170 board to pair with an unlocked Skylake CPU, we like Gigabyte's GA-Z170-HD3. This $115 mobo has everything the enthusiast needs without a lot of frills. Despite its wallet-friendly price, the GA-Z170-HD3 offers a full complement of PCIe expansion slots, an M.2 slot, three SATA Express connectors, and a smattering of USB 3.0 ports. For a little more than a Benjamin, this board isn't missing much. SLI support and USB Type-C ports are the only features we didn't see that some builders might want.


Gigabyte GA-Z170X-UD3

If you've gotta have SLI support, Gigabyte's GA-Z170X-UD3 lets builders install multiple Nvidia graphics cards. It also adds a few other niceties compared to our budget pick. This board packs two M.2 slots, an Intel Gigabit Ethernet controller, a fancier Realtek ALC1150 audio codec, and an Intel Alpine Ridge USB 3.1 controller with both USB 3.1 Type-C and Type-A ports. Oh, and LEDs along the audio paths. For the price, we think it's a steal.


Gigabyte Z170X-Ultra Gaming

If you're building with an eye toward the future, Gigabyte's Z170X-Ultra Gaming looks like a great value. This board has a USB Type-C port that carries both Thunderbolt 3 and USB 3.1 Gen2 signals, and it's also certified for the USB Power Delivery 2.0 spec. That means compatible devices can get as much as 100W of charging power through that do-it-all port. Gigabyte also throws in a U.2 connector for 2.5" NVMe SSDs and extensive LED accents.

High end
 

Product Price Notable needs
Gigabyte GA-X99P-SLI $249.99 Intel LGA2011-v3 processor, ATX case
Asus X99-A II $229.99

We think that builders with high-end systems in mind should start weighing Thunderbolt 3 compatibility when picking out new parts. Following that train of thought, our primary option for the higher end is Gigabyte's GA-X99P-SLI. This board uses Intel's Alpine Ridge controller to provide both high-speed USB 3.1 and Thunderbolt 3 connections through its single USB 3.1 Type-C port. This Gigabyte board is down a couple ports in its rear cluster compared to the X99-A II below, but the tradeoff could be worth it if you need the X99P-SLI's unique feature set. They're both the same price, so pick the board most suited to your needs.


Gigabyte GA-X99P-SLI

Keep in mind that the X99P-SLI may need a BIOS update to function properly with Broadwell-E chips. This board doesn't include Gigabyte's handy Q-Flash Plus feature, which lets builders update the motherboard's firmware with nothing more than a USB thumb drive and a power supply. If you don't already have a Haswell-E CPU lying around, you might have to borrow one somehow to get the X99P-SLI up to date for Intel's latest.

If you can live without built-in Thunderbolt and would rather not chance Broadwell-E compatibility, we think Asus' X99-A II is a great pick. The X99-A was our favorite motherboard for Haswell-E CPUs when they were the hot new thing, so we're happy to see that the company has updated the board for Broadwell-E. Like its predecessor, this board offers everything we'd really want in a high-end desktop and nothing we don't.


Asus X99A-II

This refreshed board has USB 3.1 Type-A and Type-C ports, a U.2 connector for 2.5" NVMe SSDs, an M.2 slot, Realtek ALC1150 audio, and the all-important RGB LED lighting. Like its predecessor, we think the X99-A II is all the X99 motherboard one might ever need unless it doesn't satisfy some strange corner case.

We have some bad news for you when it comes to memory. Prices have been rising sharply, sometimes to the tune of 30% or so. There isn't much to be said about that fact other than "buy now, and buy plenty." Nevertheless, we still consider that a good amount of RAM is still fairly affordable and a good investment for your PC. We've picked out some sets at different price and capacity points, as you can see in the table above.

We think there's no reason at all to consider anything but 8GB in an entry-level build these days. It also doesn't cost a whole lot extra to step up to 16GB of RAM any longer. If you use Photoshop or other creative applications in tandem with a lot of open browser tabs, 16GB of RAM is starting to become a baseline, not an upgrade. Even 32GB of RAM might not be outlandish for the heaviest multitaskers.

Intel's official spec for Skylake-compatible DDR4 RAM is DDR4-2133 running at 1.2V, but we've used significantly faster DIMMs like DDR4-3000 in our CPU and motherboard test rigs without issue. Given the small price premium and potential increases in bandwidth that faster DDR4 offers, we think it's a worthy upgrade to get the speedier RAM if you have room in the budget.

If you're building an X99 system, be sure to choose (or assemble) a kit with four DIMMs to reach the capacity you want. Broadwell-E CPUs need four DIMMs to take full advantage of their quad-channel memory controllers. Broadwell-E also boosts compatible memory speeds to DDR4-2400 out of the box, so there's no reason to stick with DDR4-2133 for anything but budgetary reasons.
