3500xGame to the Extreme!

If you’re looking to play all the latest games on a 4K or ultra-wide monitor, you’re going to need extreme processing power. And that’s what the $2,500 Gaming PC Build delivers – every component has been selected with one and only one goal in mind: maximum ultra-high-resolution performance for $2,500, with a healthy dose of style thrown in!

This Month’s Build, Powered by AMD and Nvidia!

For October 2025, the $2,500 Gaming PC Build features AMD’s shockingly-fast Ryzen 7 9800X3D, the best gaming processor on the market. Intel’s processors can’t even come close to it. The 9800X3D is backing up a powerhouse of a GPU, the Nvidia GeForce RTX 5080 16GB, which makes it into this build thanks to a massive price drop over the past few months!

But this build is about more than just a fancy CPU and GPU. For starters, you’re getting 32GB of DDR5-6000 RAM and a high-end 2TB PCIe Gen 4 solid-state drive to store your entire gaming collection. Defining the build is the classy and Corsair 3500X case, in which you’ll be mounting a 360mm liquid CPU cooler and a potent 850W Gold-rated power supply. In other words, this build is great in every way! Also notable this month is the white color motif – which includes the case, motherboard, cooler, and power supply!

    CPU –

    AMD Ryzen 7 9800X3D

    $477
    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

    The 9800 X3D is so dominant that Intel's next-gen CPUs can't even be considered for gaming!
