$2500 Build

If you're looking to play all the latest games at 4K, you're going to need some serious processing power. And that's what this build delivers - every component has been selected with one and only one goal in mind: maximum high-resolution performance for $2,500! And here at The Tech Buyer's Guru, we buy the hardware first and then run the benchmarks to make sure you'll have the best possible experience. We're not just throwing together parts lists like a lot of other sites!

For February 2017, we carry forward the huge updates that we first unveiled upon the launch of Intel's new Kaby Lake platform in January. This includes the Core i7-7700K quad-core processor, the fastest chip ever released, and the first one legitimately capable of punching through the 5GHz barrier with just a little bit of overclocking luck. We pair it with a Z270-based motherboard, offering the latest in connectivity options, LED lighting, and of course built-in support for the 7700K. To power you through your gaming sessions, we recommend dual GeForce GTX 1070 8GB video cards in SLI. To see how GTX 1070 SLI performs, just check out our recent 4K Showdown, which demonstrated that on average, this setup will match or beat the much more expensive Titan X Pascal!

A major trend in PC gaming today is the use of fully-controllable RGB lighting. We know some people are going to be more excited about this than others, but we want to lay out all the options. So this build now features an Asus motherboard and dual Asus graphics cards offering the Asus Aura lighting system for fully-synced RGB effects We also provide an optional upgrade to an Aura-compatible RAM kit, in case you'd like to fully-sync your internal components. Once Aura-compatible cases hit the market, they'll be added as an option too. For now, we stick with our very favorite case, the SilverStone Primera PM01, which is offered in black with red lighting, or white with blue lighting.

As always, to see our previous part picks and prices, just flip to the $2,500 Build Archive, or see our TBG PC Build Comparison Page to compare this system to all our other builds, spec-for-spec. By the way, if you'd like to see what this system looks like built up, we strongly encourage you to check out our 2016 Guide to Assembling an Ultra-High-End PC, which will walk you the process of building a system a lot like this one.

The $2,500 Extreme 4K Gaming PC - February 2017


    Intel Core i7-7700K

    Intel's brand-new Core i7-7700K, launched on January 3rd, is the perfect CPU to power a high-end gaming system, as well as the bang-for-the-buck pick to run at 4K. It's clocked at 4.2GHz, and has headroom to be overclocked way beyond that, perhaps even hitting 5GHz. Of course, that will generate some serious heat, which is why we suggest nothing less than a 240mm liquid CPU cooler, listed later in this guide.

    The Guru's Tip:

    The 7700K actually runs at 4.4GHz with a quad-core load thanks to its aggressive Turboboost. The older Core i7-6700K only ran at 4GHz under identical conditions.


    Asus ROG Strix Z270E Gaming

    Hot off the assembly line, this model features plenty of high-end features, despite a mainstream price. It boasts six USB ports (including a cutting-edge USB 3.1 Type-C connector, the future of I/O connectivity), dual M.2 slots for high-speed SSDs, and ultra-high-end audio. You even get built-in 802.11ac networking, a very rare feature in this price range. And, of course, it supports SLI'd video cards in an x8/x8 configuration, which you'll be running in this system.

    The Guru's Tip:

    Asus is now bundling high-bandwidth (HB) SLI bridges with its Z270 boards, saving you the $40 cost of buying an after-market model. Our in-depth SLI benchmarks show that the dual links provided by the HB SLI bridge increase performance by up to 7%!

    Video Card:

    Asus GeForce GTX 1070 8GB ROG Strix OC

    To get playable framerates at 4K, you need a seriously-powerful GPU. Well, make that two GPUs! In our new 4K Gaming Showdown, we ran five configuration through its paces, including GTX 1070, 1070 SLI, GTX 1080, 1080 SLI, and Titan X Pascal. We concluded that 1070 SLI provides an awesome 4K experience for the lowest possible cost. In fact, it's a bit faster than the Titan X Pascal, despite coming it at hundreds of dollars less! By the way, as of our latest update, the overclocked version of this card is now around the same price as the standard model, so it's now the one we recommend.

    The Guru's Tip:

    One of the great features of the GeForce lineup is G-Sync, which matches framerates to the frame output on compatible displays for stutter-free gameplay. See all our recommended monitor picks, including 1440p and 4K models, in our Monitor Buyer's Guide.

    Video Card:

    Asus GeForce GTX 1070 8GB ROG Strix OC

    Adding a second GTX 1070 is what makes this system a serious 4K gaming machine! The 1070 Strix by Asus has two distinct advantages over its rivals: first, it has the biggest, most powerful cooler to grace any 1070 model (an important feature when running in SLI), and second, it's equipped with the Aura lighting system, which will sync up with this build's Asus motherboard to provide awesome RGB effects.

    The Guru's Tip:

    We recommend you set up Windows with just one card inserted, and then once all drivers are installed, shut down the system, insert the second card and the SLI bridges, and then boot up the system. You'll likely need to enter the Nvidia control panel to enable SLI. It may require a reboot before it takes effect.


    Corsair 2x16GB Vengeance LPX DDR4-3200 White

    We go big here, choosing an awesome 32GB kit from Corsair, the Vengeance LPX DDR4-3200. You'll never need more RAM than this, but if you do, you'll still have two free RAM slots to fill! Based on our in-house DDR4 Gaming Benchmarks, we know DDR4-3200 is the best pick for a system like this. Be wary of guides that suggest DDR4-2133 or DDR4-2400, which will seriously handicap the Core i7-7700K processor.

    The Guru's Tip:


    The latest trend in PC building is the move to fully-customizable RGB lighting. This build's motherboard and video cards are equipped with the Asus Aura RGB syncing system. Want to include your RAM in the lightshow? Well, then step up to the new G.Skill TridentZ 4x8GB DDR4-3200 RGB kit with Aura compatibility. It costs a more than Corsair's standard DDR4-3200 RAM, but if you want the truly "custom" look, it's the way to go!

    Solid-State Drive:

    Samsung 850 Evo 1TB

    With most of the big players leaving the high-end SSD market, Samsung is now alone in selling a big, ultra-fast SSD at a great price, making the 850 Evo 1TB the go-to choice for this build. With current-gen games requiring 30-40GB of storage, you need a big drive to hold more than a handful of games, and running them off an SSD means boot times are nearly instantaneous!

    The Guru's Tip:

    This drive offers the best value among high-end drives. That being said, if you want the latest and greatest, step up to the new Samsung 960 Evo 1TB M.2 drive, which is up to 5x faster than the 850 Evo in sequential I/O tasks!

    Hard Drive:

    Toshiba P300 3TB

    Hard drives are pretty utilitarian at this point, but for a system of this caliber, we want a big, high-quality drive. Therefore, we recommend Toshiba's 3TB model, as it offers an excellent balance of speed, capacity, and reliability.

    The Guru's Tip:

    If you don't foresee having a need for more than 1TB of storage in the near future, we'd strongly recommend just skipping the hard drive for now. There simply is no comparison between a hard drive and an SSD in terms of speed. The only reason we'd go with this drive is for media storage, such as music, photos, and videos.


    SilverStone Primera PM01

    This new case from SilverStone embodies all that is right with ultra-modern case design. Why do we love this case so much? Because it has practically unlimited airflow, courtesy of its fully-meshed front panel, four pre-installed 140mm fans (three with LED lights), and its hidden drive cages. You also get a PSU cover that keeps things nice and neat once your build is complete. Just note that as with many new cases, this one will not fit an optical drive.

    The Guru's Tip:

    Want to learn how to build up a system in the SilverStone Primera PM01? Check it out in our step-by-step Ultra-High-End Assembly Guide. Note that we used the white version, perfect if you want to class it up a bit. SilverStone has plans for a version of the PM01 with built-in compatibility with the Asus Aura RGB lighting system used in this system's motherboard and video cards. It should be arriving in Q2'17 based on what we saw on display at CES in January.

    Power Supply:

    EVGA Supernova G2 750W

    We've been recommending (and using!) EVGA's Supernova line since it was released, and it appears in a number of our other build guides in various sizes. This model, designed for EVGA by SuperFlower, offers 750W of Gold-rated power for around the same price as other less-impressive models. In addition to abundant power, it offers a zero fan mode at loads under ~400W, right where this system will operate. Plus, it's backed by EVGA's market-leading 10-year warranty!

    The Guru's Tip:

    While we previously recommended the Supernova P2 750W for this build, that Platinum-rated model has jumped in price unexpectedly. We'll hopefully bring it back when the price is competitive again.

    CPU Cooler:

    Corsair Hydro H100i v2 Liquid Cooler

    To keep a dual-GPU system running optimally, you need a CPU cooler capable of moving a lot of waste heat out of your system as quickly as possible. We therefore recommend Corsair's Hydro H100i V2 240mm liquid cooler, which we reviewed here. It features a higher-efficiency radiator and quieter fans than most other liquid coolers, along with unbeatable performance.

    The Guru's Tip:

    The optimal setup is to have your radiator mounted to the top of the case, with fans blowing through the radiator and out of the case. You'll often see builds with the cooler mounted up front, pulling in cool outside air and blowing super-heated through the case. This lowers CPU temps at the expense of the system as a whole, and would be awful with a dual-GPU setup.

    Operating System:

    Microsoft Windows 10 Flash Drive

    Windows 10 represents a huge leap forward from Windows 8.1, and now that Microsoft has released the Anniversary Update, it's better than ever. And you will definitely want W10 for gaming, as it includes the new, cutting-edge DX12 low-level API, which provides higher performance and better graphics in PC games, as seen in such hit titles as Rise of the Tomb Raider and Battlefield 1, as well as the DX12-only title Gears of War 4.

    The Guru's Tip:

    Windows will install in around 5 minutes thanks to the incredibly-fast USB 3.0 interface!
