As we approach the holiday season, the Haswell-E and X99 platform has only been on the market for almost three months. With a rushed launch, the motherboard manufacturers raced to get their models out to market, but as time has moved on we now have the bulk of the X99 landscape to examine for potential.

From the North America perspective, a website such as Newegg has 32 LGA2011-3 motherboards on offer for Haswell-E processors (at the time of writing). This splits down to 11 from ASRock, 6 from GIGABYTE, 5 from ASUS, 4 from MSI (Gaming 9 seems absent) and 3 from EVGA. Almost all of these are ATX sized due to the potential for extreme GPU configurations, with three/four in the mATX format.

Unlike graphics cards, it is more difficult to partition off motherboards as each manufacturer has a completely different set of bells and whistles under the hood. So while most motherboards might get similar results in the CPU testing (depending on MultiCore Turbo), this can lead to differing performance levels in our system benchmark suite.  So while we have only tested several motherboards for review and another few internally, we can at least look at the specifications and make some reasoned judgments based on the BIOS/software and hardware within.

Our holiday guide for X99 is split into the following sections:

  1. X99 on a Budget; X99 with Bells and Whistles (this page)
  2. X99 at $300
  3. X99 with No Limits
  4. X99 in microATX

Both of the motherboards mentioned on this page were part of our initial X99 roundup, featuring four of the most high profile products for the X99 launch, one from each of the main manufacturers. For an indepth look into X99, start here.

X99 on a Budget: MSI X99S SLI PLUS at $220

One of the surprises in our initial X99 roundup was the MSI X99S SLI PLUS – it ended up being a cheaper X99 motherboard that offered good performance at stock while near the bottom of the X99 price bracket and retaining an element of color coordination and all-black style.

For feature set, the motherboard gives M.2 and SATAe support with a Realtek ALC892 providing the audio and an Intel NIC for good measure. The X99S SLI PLUS had a slight deficit, giving lower performance than others when overclocked as well as a slightly higher power consumption, but the DPC Latency and CPU results at stock were near the top of the pile.

Part of what made me give the SLI PLUS an award came from the ability for MSI to react to suggestions. The BIOS team at MSI took on board many of my 8-series criticisms and implemented fixes, such as ordering the OC menu, to help improve the experience. MSI still has one of the best update software packages for the OS, and given the price point offered a good entry into the X99 market when paired with an i7-5820K.

X99 with bells and whistles: ASUS X99-Deluxe at $385

Another motherboard from our initial coverage, the ASUS X99-Deluxe has a number of unique features that sets it apart from the other manufacturers. Due to popular request, a lighting system has been added to help users install graphics cards for the best lane allocation, and an onboard Auto-XMP switch is in place to help users get the speed from their memory without having to enter the BIOS.

The design is also a plus point, with the Crystal Sound 2 cover matching the heatsinks and giving the system a premium feel. For the hardware we get two SATAe ports, a vertical M.2 x4, a bundled Hyper M.2 x4 PCIe card, 3T3R ‘tri-stream’ 802.11ac WiFi, dual Intel network ports, Realtek ALC1150 audio with PCB separation/filter caps/de-pop circuitry and a bundled fan header PCB to allow system builders to be more versatile with the fans giving nine headers in total that are DC and PWM controllable.

While stock performance does not take advantage of MultiCore Turbo, any overclock from using TPU to manual overclocking gives good performance. The BIOS builds on the iterative nature of EZ Mode and Advanced mode, with the software being relatively easy to use.  Whereas the SLI PLUS is a nice fit for the i7-5820K, the Deluxe goes well with the full-fat i7-5960X

X99 at $300

    I'm surprised the MSI X99S XPOWER ( isn't on your no-limits list. Spec for spec it offers the same features as the rampage V, even surpassing it in a couple of areas, while maybe lagging behind in couple of others. All that for almost $100 cheaper with better OC tools, and at least in my opinion better aesthetics.

    Looking at specs, I hadn't actually realized the x99s was budget.

    The RoG brand name carries a lot of weight.

    Generation after generation, the leaders in Extreme OCing.

    Does the Asus deluxe support the Samsung xp941?
  • kwerboom - Thursday, November 27, 2014 - link

    Will Anandtech a DDR4 Memory Roundup like either or soon?
  • Senti - Thursday, November 27, 2014 - link

    The usual review from Ian – he doesn't even look at what he is reviewing, just copy-pasting the same phrases. "x16/x8/x8/x8/x8/x8/x8 for 7-way compute" on Extreme11 with only 5 PCIe slots? Sure!

    Yeah, I noticed that too, pretty sloppy!

    Also as an aside, I would really like to know the exact PCIe lane allotment for all of these boards. In-fact I would LOVE to see a PCIe lane assignment diagram standard from EVERY motherboard, it would be good to see it in the manual, especially these days as this stuff is getting more and more complex. I would like to AT LEAST see this sort of thing in EVERY mobo review. There is pretty much no excuse for not including that in a review.

    $476-$650? Ouch... that at least used to be the price range for a dual-socket board.
  • Antronman - Monday, December 8, 2014 - link

    Dual sockets are even cheaper than that, these days.
  • eanazag - Tuesday, December 9, 2014 - link

    X99 board prices are ridiculous.

    Yes, you can consider dual socket systems. What you can expect in 2P systems: no overclocking (CPU or memory); Intel Xeon CPUs are lower clocked, but have larger caches for more money; very basic audio (no 5.1 or 7.1 possible) or no audio; Xeon CPUs come with no heatsink/fan; may not support SLI and CF, yet have multiple slots; no WiFi; M.2 support might be tough to find; for gaming a $300 Haswell CPU will perform better. You're getting a crazy amount of threads to play with designed to run 24/7, yet thread scaling in most apps won't help you out. You'll need Windows 8.x Pro to use the second socket. 8.x Home only supports 1 socket.

    So if you wanted to medicore game and fold at home and GPU mine and run a NAS and encode some movies at the same time, then a 2P system makes sense.
