NVIDIA's super-powered GeForce RTX 4090 has arrived and to celebrate we designed the highest-end PC we could imagine to go along with this killer card. We put together a breakdown of everything new with the GeForce RTX 4090, including the new-and-improved DLSS 3 and third-gen Ray Tracing Cores! With a card this good, why would you settle for anything less than an unbeatable behemoth?

The Build:

Processor: AMD Ryzen 9 7950X Raphael AM5 4.5GHz 16-Core Boxed Processor

AMD's new flagship processor, the Ryzen 9 7950X is a stunningly powerful CPU that launched with industry-leading speeds. And, as it's fully compatible with all NVIDIA GPUs, it is absolutely the processor for this build. With DDR5 and PCIe 5.0 support, it is a must-have if you want every ounce of power on the market. And don't forget an AIO for cooling!

Motherboard: Gigabyte X670E AORUS XTREME AMD AM5 eATX Motherboard

The last thing you want to do with a build like this is get stuck with a motherboard that can't keep up. With DDR5-5200, WiFi 6, and PCIe 5, Gigabyte's X670E AORUS XREME doesn't just keep up, it leads the pack. Plus, the gorgeous aesthetics certainly don't hurt!

Graphics Card: MSI NVIDIA GeForce RTX 4090 Gaming X Trio Triple Fan 24 GB GDDR6X PCIe 4.0 Graphics Card

The NVIDIA GeForce RTX 4090 is the reason for the season and very much the centerpiece of this build. There is absolutely nothing like this beast of a card anywhere else on the market and it will absolutely crush any game or creative endeavor you put in its path. With 24GB of GDDR6X and 16,384 CUDA Cores, it's sitting very pretty at the top of the charts.

RAM: G.Skill Ripjaws S5 64GB (2 x 32GB) DDR5-5200 PC5-41600 CL36 Dual Channel Desktop Memory Kit

16GB? Nope. 32GB? Better, but still not enough. 64GB? Now we're talking. G.Skill's Trident Z5 2 x 32GB is exactly what a build like this needs. Not only is it lightning-fast DDR5-5200, but it leaves enough room for an extra set if you feel the need to double up!

Storage: Inland Performance Plus 8TB 3D TLC NAND PCIe Gen 4 x4 NVMe M.2 Internal SSD

Why use multiple storage drives of varying power and speed when you can just use one with an absolutely massive amount of storage space? The Inland Performance Plus has eight terabytes of storage capacity crammed into a tiny NVMe drive. And hey, if you need more space, there's always room for more!

Power Supply: MAINGEAR IGNITION 1200 Watt 80 Plus Platinum ATX Fully Modular Power Supply

A computer with this much power is going to have a huge energy draw. This 1200 Watt MAINGEAR IGNITION does go a bit beyond what is absolutely required, but that extra bit of power headroom is super useful if you intend to overclock or upgrade anytime soon. Plus, with an 80 Plus Platinum rating, you're getting fantastic efficiency, keeping your electricity costs down!

Case: Lian Li Lancool II MESH Performance Type C Tempered Glass ATX Mid-Tower Computer Case

The Lancool II MESH Performance might not be the flashiest case (who needs flash when you have power?), but it is big. And with the NVIDIA GeForce RTX 4090, you absolutely want a big case to keep your clearances wide and your airflow high
