The Best $5000 Dream Machine Gaming PC Build – September 2025
Build the Gaming System of your Dreams!
If you want to build a dream gaming system, but can’t stand the idea of having another huge desktop by your side, stop dreaming and jump into a new reality! This build has all the power you could want, packed into an awesome high-end chassis that performs as great as it looks. It’s everything you want in a killer gaming PC!
This Month’s Build, Powered by AMD and Nvidia!
For September 2025, the $5,000 Dream Machine Gaming PC Build is everything you could want in a gaming rig and more, with the best combo of performance and aesthetics possible. It starts with AMD’s game-conquering Ryzen 7 9800X3D 8-core, 16-thread CPU, which has Intel busy playing dead. And you’ll make use of all of its power, because this system will be pushing out a massive number of frames thanks to the insane Nvidia GeForce RTX 5090 32GB, which is a shocking 30% faster than the already absurd RTX 4090, and draws the power to prove it: 575W, more than most full gaming PCs!
But that’s not all… this build is packing premium gear everywhere else! 64GB of fast DDR5-6000 CL28 RAM will assure the CPU has plenty of bandwidth and room to perform. For storage, this system gives you 4TB of blazing-fast PCIe Gen 5 storage. To keep things cool, this system uses a high-powered 360mm liquid CPU cooler with a built-in screen. Feeding the system is a quiet and ultra-efficient 1200W Platinum-rated power supply. Finally, the system comes together in the sweet-looking be quiet! 900 FX case, which will really show off the build!

This CPU is the ultimate gaming processor, regardless of price.While there are chips that can beat this one in productivity, this 8-core gem is a gamer's dream chip!
