The Best $5000 Dream Machine Gaming PC Build – October 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 October 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 CL30 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 simply- massive 420mm liquid CPU cooler. Feeding the system is a quiet and ultra-efficient 1200W Platinum-rated power supply. Finally, the system comes together in the sweet-looking Arctic Xtender case, which will really show off the build!

The DIY Build

CPU –AMD Ryzen 7 9800X3D
$477The Guru’s TipAMD’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.While there are chips that can beat this one in productivity, this 8-core gem is a gamer's dream chip!
-
Motherboard –Asus ROG Strix X870E-E
$454The Guru’s TipThis X870E board from Asus allows you to tap into the full potential of AMD’s cutting-edge AM5 platform. You get a potent 18+2+2 power design with 110A Smart Power Stage , a PCIe Gen 5 video card slot plus an additional PCIe slot, five M.2 slots (three being Gen 5, two being Gen 4), and built-in WiFi 7. On the back you have 13 USB ports, including two cutting-edge USB 4 (40Gbps) ports. It also has great aesthetics, making this an all-around premium choice!This board has all the bells and whistles!
-
Video Card –Asus GeForce RTX 5090 32G TUF
$2850The Guru’s TipHail to the king! The absolutely mind-blowing RTX 5090 32GB goes beyond extreme, beating the legendary RTX 4090 by 30%, an incredible gen-on-gen leap in performance. while also offering a whopping 32GB of VRAM (which will never be maxed out!). And this model from Asus offers great cooling thanks to the massive yet attractive triple-slot, triple-fan cooler and flow-through fin-stack!We've seen 5090 prices fluctuating dramatically over the past few months, and our hunch is that stock is dropping again after improving for a while.
-
Memory –G.Skill 2x32GB Trident Z5 Neo RGB DDR5-6000 CL30 EXPO
$255The Guru’s TipTo 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 making the most of the AM5 platform. It allows for the highest overall performance thanks to running in 1:1 sync with the memory controller. And this 64GB Trident Z5 Neo kit from G.Skill is specially designed for AM5, thanks to the excellent 30-40-40-96 AMD EXPO timings.64GB is honestly all you'll ever need, even in a Dream Machine!
-
Solid-State Drive –Samsung 9100 Pro 4TB PCIe Gen 5
$399The Guru’s TipFor 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!In terms of a "gaming" drive, you really can't do better than this model - it offers a tremendous amount of speed, without going wildly overboard in terms of $/GB!
-
Case –ARCTIC Xtender VG (Mirror Black)
$190The Guru’s TipFor its very first case, cooling expert Arctic knocked it out of the park. The Xtender is serious looker, thanks to the glass panels and bright ARGB fans (two 120mm in the rear and three 140mm on the side). But those fans also provide excellent cooling, and the top of the case offers space for massive liquid coolers. And a neat effect is the mirrored glass, which only reveals the inside when the ARGB lighting is on.The chassis also includes a PCIe Gen 4 riser cable to vertically mount the GPU. That's a nice bonus thrown in practically for free, but we'll note that all modern GPUs use the PCIe Gen 5 interface, so there'll be a small loss of performance if you choose to use the cable (it's totally optional).
-
Power Supply –be quiet! Straight Power 11 Platinum 1200W
$233The Guru’s Tipbe quiet! originated the silent PSU, and the Straight Power 11 is a perfect example of the latest innovations the company has to offer. Featuring 1200W of Platinum-rated power, a fully-modular cable design, and a high-end Silent Wings 3 135mm fan with funnel-shaped intake shroud, this is an exceptional choice for a premium PC build!This system will pull about 750W at maximum load, so this PSU will have plenty of headroom to spare. And the truth is that future CPUs and GPUs (which we expect you'll eventually upgrade to) will almost certainly draw much more power, so you'll be prepared with this unit!
-
CPU Cooler –Arctic Liquid Freezer III Pro 420mm
$113The Guru’s TipThere is no better AIO cooler on the market than Arctic’s massive LFIII 420mm, with its huge radiator (420mm wide and 38mm thick), and triple P14 Pro ARGB fans. It also has a sleek cabling system, providing a totally streamlined look. Despite its competitive price, this cooler is definitely the cream of the crop!Mount this radiator to the top of the chassis as an exhaust.
-
Operating System –Windows 11 Home (USB) @Newegg
$139The Guru’s TipWindows 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.This is absolutely the OS you want on your system to take full advantage of the advanced platform.
