Choose Your CPU Platform

Our custom PC builder supports seven gaming CPU platforms plus two dedicated workstation builders. Click through to configure your build:

AMD Platforms

  • AMD Ryzen 9000 Series (AM5) — The latest AMD platform. Ryzen 5 9600X to Ryzen 9 9950X3D. Best-in-class gaming performance with 3D V-Cache options.
  • AMD Ryzen 8000 Series (AM5) — Integrated graphics on select chips (8600G, 8700G) for display output without a dedicated GPU. Great value mid-range option.
  • AMD Ryzen 7000 Series (AM5) — Proven AM5 platform. Ryzen 5 7600 to Ryzen 9 7950X. Excellent price-to-performance across the range.
  • AMD Ryzen 5000 Series (AM4) — Our budget platform. Ryzen 5 4500 to Ryzen 9 5900XT, plus the Ryzen 7 5800X3D. DDR4 memory and cheaper motherboards keep the total build cost right down.

Intel Platforms

Workstation Builders

Building for work, not just gaming? Our dedicated workstation configurators use professional silent and solid-panel cases (be quiet!, Fractal Design, ASUS ProArt) with up to 192GB DDR5 — tuned for CAD, 3D rendering, video editing, photography and AI.
