The Best $3,000 Elite RGB Gaming PC Build – June 2021

By Ari Altman | Published June 2, 2021 | Updated June 16, 2021

Critical Update: if you actually want to start gaming on a new PC any time before Fall 2021, you have two options: try to grab one of the few pre-built PCs still for sale, or build up a PC using an older GPU that you have on hand. That’s because GPUs are sold out worldwide due to the latest cryptocurrency mining crisis. We present both options to you in this guide.

If you want a $3,000 Gaming PC Build that’s a true showcase, not just another black box, then this is the one for you! In addition to the best gaming components available, it sports the latest in addressable RGB lighting and case design! We didn’t just add “RGB” to the name of this build without making sure it delivered on the looks front. The case fans, cooler, RAM, and motherboard can all be color-coordinated to make your build more than just blingy – it will be a work of art! Seriously, of the two dozen builds we profile on this site, the $3,000 Gaming PC Build is the one we’d be buying with our own money, because it looks awesome and has performance to spare!

For June 2021, the $3,000 Gaming PC Build features the trend-setting Corsair iCUE 5000X RGB case plus Corsair’s premier 360mm RGB AIO liquid cooler, which makes this system stand out like no other build. But of course it’s also a deadly-serious gaming machine. Inside you’ll find AMD’s blazing-fast Ryzen 7 5800X 8-core, 16-thread CPU and a high-end Asus X570 motherboard that will integrate with the Corsair iCUE RGB system. For the GPU, we recommend an RTX 3080 10GB GPU. For storage, we go with a 2TB PCIe solid-state drive along with 32GB of Corsair DDR4-3600 RGB-lit RAM. See this build and questions in our YouTube review of the 5000X case:

The Pre-Built Option

  • The Ultra-High-End Gaming PC

    Skytech Siege 3.0 5800X/RX 6900XT


    Step into serious ultra-high-end gaming while everyone else waits months for components to come back in stock! This awesome pre-built from Skytech is packed with game-crushing gear, including the AMD Ryzen 7 5800X 8-core, 16-thread processor and the AMD Radeon RX 6900XT 16GB GPU, which matches the GeForce RTX 3080 Ti 12GB in performance but offers a lot more VRAM. Also onboard is a 360mm liquid CPU cooler, 16GB of DDR4-3200 RAM, a 1TB PCIe-based SSD, and a 750W Gold-rated power supply. The system is wrapped up in the stylish Thermaltake S300 chassis, which really brings this sweet system together!

    The Guru’s Tip

    We have absolutely no idea why Skytech is offering this at such a low price, so grab it fast before everyone else catches on!

The DIY Build

  • CPU

    AMD Ryzen 7 5800X

    Based on AMD’s revolutionary Zen 3 architecture, the Ryzen 7 5800X is a truly fantastic processor. It has 8 core and 16 threads all running from a single complex for maximum efficiency, with boost up to 4.7GHz. That means it’s actually the fastest processor available for single-threaded tasks, which many tasks still are.
    The Guru’s Tip

    This CPU does not come with a cooler, and anything you'd get in the box couldn't handle it anyway, so make sure you pick up the massive liquid cooler we recommend later in this guide!

  • Motherboard

    ASUS ROG Strix X570-E Gaming


    Featuring AMD’s most advanced chipset, the X570, this board is built to be the best! It offers up a robust 12+4 power solution, dual PCIe Gen 4 M.2 slots, 802.11ax networking, 2.5Gbps LAN, eight USB ports (including Type-C), and onboard diagnostics.

    The Guru’s Tip

    Most importantly for this build, this board has the best RGB controller and software in the industry, and it's fully compatible with Corsair gear too!

  • Video Card

    EVGA GeForce RTX 3080 FTW3 Ultra @EVGA

    Nvidia launched the greatest GPUs of all time with its new RTX 3000 series, which blows away all previous video cards, including the once mighty RTX 2080 Ti. The RTX 3080 offers 30% higher performance for a lot less money, which is an unprecedented generational leap. This EVGA model is among the coolest-running, quietest, and best-looking models on the market, and it comes with unparalleled customer service.
    The Guru’s Tip

    The built-in video on Intel's CPUs never came in as handy as it does today, with all GPUs sold out worldwide!

  • Memory

    Corsair 4x8GB Vengeance RGB Pro DDR4-3600 C16 @Newegg

    We go big with 32GB, which will be more than enough for any usage scenario imaginable. And at 3600MHz with 16-19-19-39 timings, this kit provides incredible speed in addition to its capacity. Of course, it also looks the part, with the best looking RGB lighting on the market! Plus, with all four slots filled, you’ll really get a light show! Fun fact: this particular kit is a limited-edition model, available only from Newegg as of our latest update!
    The Guru’s Tip

    The lighting on this RAM can be easily controlled with Corsair's iCUE software.

  • Solid-State Drive

    Samsung 970 Evo Plus 2TB


    Samsung offers up a blazing-fast, high-capacity solution with its 970 Evo Plus 2TB. Combining TLC NAND flash, an advanced controller, and the PCIe Gen 3 interface, it’s the best SSD in its class!

    The Guru’s Tip

    While you can use a PCIe Gen 4 drive in this system, it will pay very few dividends for gaming purposes.

  • Case

    Corsair iCUE 5000X RGB

    There’s simply no better case to use as a high-performance RGB showcase than the glass-covered 5000X from Corsair. It has four glass panels (front, top, and two sides), and includes three SP Elite RGB fans and a Node Core RGB controller pre-installed. Load it up with the additional gear we recommend in this guide and you will have an amazing performer and a system with looks that can’t be touched!
    The Guru’s Tip

    Corsair's iCUE software, which is what this case is named for, allows extensive control over RGB gear, including Corsair coolers, fans, RAM and peripherals, and even Asus motherboards like the one we recommend!

  • Fan

    Corsair iCUE SP120 RGB Elite

    This fan will connect right up with the controllers built into the case, allowing it to sync both for RPM and lighting control with the stock fans.
    The Guru’s Tip

    In this build, you'll be mounting this fan in the rear of the chassis, where it will complement the three SP Elite front fans and the fans on the Corsair 360mm CPU cooler.

  • Power Supply

    Corsair RM850x


    Corsair is legendary in the PSU market, being among the first to develop truly-premium offerings. This 850W Gold-rated unit power supply has more than enough power to support any combo of CPU and GPU. And the modular cables will keep the build neat while the zero fan mode keeps it quiet at idle!

    The Guru’s Tip

    This model is fully-compatible with the slick individually-sleeved cables listed below, which will give your system a truly custom look!

  • Cable

    Corsair Individually Sleeved PSU Cables Pro Kit – White @Newegg


    These cables will pair with the Corsair power supply listed above, providing the ultimate custom look for your PC!

    The Guru’s Tip

    The kit includes all the cables you'll need for this build and then some! Note that they sell out constantly and are completely optional, so you can always pick them up later on.

  • CPU Cooler

    Corsair iCUE H150i Elite Capellix White @Newegg

    For the high-powered $3,000 Gaming PC Build sporting a 10-core CPU, we recommend you go for the amazing H150i Elite Capellix from Corsair. It offers up three ML120 fans equipped with magnetic levitation bearings, along with awesome ARGB lighting that can be sync’d directly with the rest of the components spec’d in this build.
    The Guru’s Tip

    Note that this cooler includes its own RGB controller box, while you'll mount alongside the case's RGB controller box.

  • Operating System

    Windows 10 Home USB Flash Drive

    Windows 10 was a big step up from Windows 8.1, and Microsoft continues to support Windows 10 users not only with regular security updates, but with major content releases every six months. And the USB version installs in under 5 minutes, meaning you can get right into using your system!
    The Guru’s Tip

    This is the USB 3.0 version of Windows, which loads in just 5 minutes!
