The Best $3000 Ultimate Gaming PC Build – September 2025

Antec Flux ProGame Hard and Look Good Doing It!

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, we’ve pushed the limit on aesthetics with this build more than any other – it sports tasteful RGB lighting, and a glass-and-wood-paneled case to make your gear really look pro!

This Month’s Build, Featuring AMD and Nvidia!

For September 2025, the $3,000 Ultimate Gaming PC Build uses AMD’s game-dominating Ryzen 7 9800X3D, which beats everything Intel has ever offered. It’s supporting the seriously-fast Nvidia GeForce RTX 5080 16GB. And thanks to a big price drop on that 5080, we can now go for a blazing-fast 4TB PCIe Gen 5 drive, along with 32GB of DDR5-6000 RGB RAM.

To make this system really stand out, this case uses the stylish and ultra-high airflow Antec Flux Pro case, which provides an unmatched view into the interior. Keeping the CPU cool is the highest-performing 360mm liquid cooler available, and powering this system is an ultra-modern 850W ATX 3.0 power supply.

  • 9800X3D
    Click to Buy
    CPU –

    AMD Ryzen 7 9800X3D

    $472
    AMD’s 7800 X3D was impressive enough, easily beating every other CPU ever released in gaming. And despite it still holding the crown after the release of many other CPUs, AMD went and did it again, giving gamers the 9800X3D with enhanced 3D cache technology, redesigned to allow higher clockspeeds and manual overclocking. This CPU is the ultimate gaming processor, regardless of price.

    The Guru’s Tip

    This CPU does not come with a cooler, so make sure to pick up the capable liquid cooler we recommend later in this guide!
  • Tomahawk

    Motherboard –

    MSI X870 Tomahawk

    $289
    This X870 Tomahawk board from MSI gives you all the best features of AMD’s cutting-edge AM5 platform without venturing into diminishing returns – that is what the Tomahawk line has always been about! You get a potent 14+2+1 power design, a PCIe Gen 5 x16 video card slot plus two additional slots, four M.2 slots (two being Gen 5, two being Gen 4), and built-in WiFi 7. On the back you have 12 USB ports, including two cutting-edge USB 4 (40Gbps) Type-C ports and one additional Type-C port.

    The Guru’s Tip

  • RTX 5080
    Click to Buy
    Video Card –

    Gigabyte GeForce RTX 5080 16GB Windforce

    $1200
    The RTX 5080 offers nearly the same performance as the older RTX 4090, while coming in at a much lower price, and with much lower power draw. And it’s also far ahead of anything AMD offers. It offers all the latest enhancements from Nvidia, including class-leading 4th-Gen Ray Tracing cores and DLSS 4.

    The Guru’s Tip

    The 5080 has dropped in price a lot in recent months, making it a great buy for the performance on tap!
  • Team TForce DDR5-7200
    Click to Buy
    Memory –

    TeamGroup 2x16GB T-Force Delta RGB DDR5-6000 CL30 EXPO

    $104
    To get the most out of AMD’s latest CPUs, you want fast RAM, and DDR5-6000 is the sweetspot not only in terms of price, but in terms of the AM5 platform. It allows for the highest overall performance thanks to running in 1:1 sync with the memory controller. And this kit from TeamGroup features extraordinary 30-36-36-76 AMD EXPO timings.

    The Guru’s Tip

    This kit is a perfect match for this system!
  • 9100 Pro
    Click to Buy
    Solid-State Drive –

    Samsung 9100 Pro 4TB PCIe Gen 5

    $400
    For primary storage in a truly elite system, you don’t just want high-end, you want cutting-edge, and that means going Gen 5 on your SSD. Samsung has this category practically locked up with the 9100 Pro, which belts out an impressive 14,800MB/s in sequential read and 13,400MB/s in sequential write, making it about 50% faster than the best Gen 4 drives. You’ll truly be on the cutting-edge with 4TB of ultra-extreme storage on board!

    The Guru’s Tip

    You don't need a drive this fast for gaming, but you won't regret having this much fast storage for your game collection!
  • Antec Flux Pro
    Click to Buy
    Case –

    Antec Flux Pro Black

    $180
    This case is designed with one goal – maximum performance out of the box! To get you there, it features a huge mesh front panel, plus four 140mm case fans (3 in front, one in the rear), along with another two 120mm on the PSU shroud to directly cool your GPU. This is the optimal setup for extreme cooling in a PC case. We also like that it puts a more modern spin on style, trading in flashy RGB lighting for sleek wood accents along with a built-in LCD display for CPU and GPU temperature.

    The Guru’s Tip

    Antec has really hit a home run with the fan setup in this case!
  • DA850R
    Click to Buy
    Power Supply –

    SilverStone DA850R Black

    $160
    Offering up 850W of power and top-notch build quality, this PSU is a great value among high-end models. Thanks to its fully-modular cables and compact 150mm length, it’s very easy to install, allowing you to minimize cable clutter by leaving out cables you don’t need for this build. It’s also forward-looking, with both traditional video card power cables and a 12V-2×6 connector (an improved version of the 12VHPWR connector), allowing you to directly connect to any current or future GPU. The best part: thanks to its Gold-rated efficiency and zero-fan mode, the power supply will operate in silence most of the time!

    The Guru’s Tip

    This PSU will have no trouble powering this build, which will draw about 600W at maximum load!
  • LFIII
    Click to Buy
    CPU Cooler –

    Arctic Liquid Freezer III Pro 360 ARGB

    $94
    To run a high-wattage CPU, you need extreme cooling, and we suggest you go straight for this awesome 360mm liquid cooler, which offers the best performance of any 360mm AIO! That comes down to its big 38mm-thick radiator, custom-designed pump that’s superior to the generic design used by most other coolers, and the best ARGB fans on the market, the Arctic P12 A-RGB Pro models. They provide both great looks and superior performance at low noise levels.

    The Guru’s Tip

    This cooler should be mounted to the top of the chassis, blowing up and out.
  • Microsoft Windows 11
    Click to Buy
    Operating System –

    Windows 11 Home (USB) @Newegg

    $139
    Windows 11 built on everything people loved about Windows 10, and then took it to 11! It adds significant under-the-hood changes to make it faster and more secure, and of course, the interface is sleek too! Note that we’re linking to Newegg, because Amazon long ago stopped selling this physical USB version of Windows, which is the most convenient one to use.

    The Guru’s Tip

    This is absolutely the OS you want on your system to take full advantage of a modern gaming system!

  • Razer Deathadder V3

    The Ultralight Gaming Mouse –

    Razer DeathAdder V4 Pro Wireless

    $170
    Sometimes a product is so far ahead of the competition comes along that it resets the entire industry. So it is with the DeathAdder V4. The V3 had already decimated the competition, but Razer was not done winning. Featuring the same ergonomic grip as the original from years ago that set the gaming world on fire, this model now weighs a barely-there 56g, despite packing in an insane 45K DPI sensor, optical switches, wireless operation, and a shocking 150 hours of battery life. This is as cutting-edge as it gets. To have all of this in a mouse that weighs half as much as the best wireless mice from a few generations ago shows you just how far the bar has been raised!

    $530
    LG makes the best LCD-based gaming monitors, bar none. Known for its high-end TVs, it didn’t take long for LG to dominate the gaming monitor market once it entered the field, and its Ultragear line is synonymous with quality. The 32GR93U may not have a catchy name, but it certainly has the goods!
