How to Build a Linux Gaming PC: A Zorin OS Guide

Build a Linux gaming PC end to end — Linux-friendly hardware, why we pick Zorin OS, and a Steam + Proton setup that plays the Windows library. From OrcStar.

Linux gaming is genuinely good now. Between Valve's Proton compatibility layer, mature Mesa drivers, and Vulkan-native ports, most of a modern Steam library runs on Linux at close to Windows framerates. This guide walks through the whole build — picking parts that play nice with Linux, choosing a distribution, and setting up Steam so you can install and play on day one. It is the same playbook OrcStar uses for every Linux rig we ship.

1. Pick Linux-friendly hardware

GPU: AMD Radeon (RX 7000/9000, or a used RX 6000) is the easiest path — the open-source Mesa RADV driver is fast and needs no manual install. NVIDIA works well too on driver 550 and newer (RTX 30/40/50), including DLSS through Proton; just plan on installing the proprietary driver. Skip Intel Arc for gaming until Battlemage is more mature.

CPU: anything AMD Ryzen or 12th-gen+ Intel Core. Both have first-class Linux support.
Wi-Fi / Bluetooth: Intel AX210/BE200 chipsets are plug-and-play; avoid Realtek-only cards.
Motherboard: any current AM5 or LGA1700 board is fine. Save receipts for RGB software — some vendor apps are Windows-only, but OpenRGB covers most brands on Linux.

2. Assemble and boot

Physical assembly is identical to a Windows build — see our step-by-step build guide. Once posted, jump into BIOS and enable XMP/EXPO for RAM, Resizable BAR for the GPU, and set the boot mode to UEFI. Save and exit.

3. Choose a distribution — we ship Zorin OS

Any modern distro can game, but three are worth a look:

• Zorin OS 18 — Ubuntu 24.04 under the hood, a Windows-familiar desktop, and a curated Software store. This is what we install by default on OrcStar Linux rigs.
• Bazzite — immutable Fedora with SteamOS-style ergonomics. Great for a couch/HTPC build.
• CachyOS — Arch-based, tuned for gaming performance. Steeper learning curve.

Flash the ISO to a USB with Balena Etcher or Ventoy, boot from it, and run the installer. Erase the disk when prompted (no dual-boot needed for a fresh build), pick your timezone and user, reboot.

4. Install GPU drivers

AMD: nothing to do — Mesa is already there. Just run system updates.
NVIDIA on Zorin: open Software & Updates → Additional Drivers, pick the newest proprietary driver marked tested, and reboot.

5. Install Steam and enable Proton

Install the Steam Flatpak from the Software store. Sign in, then open Steam → Settings → Compatibility and turn on Enable Steam Play for all other titles, picking the latest Proton (or Proton Experimental). This is what lets Windows-only Steam titles run on Linux — most work with zero fuss. Check ProtonDB before buying a specific title.

6. What still needs Windows

Kernel-level anti-cheat titles — Valorant, Fortnite Battle Royale, some EA FC releases — are the main gap. If those dominate your library, keep a Windows dual-boot on a second SSD. Everything else, from Cyberpunk 2077 to Baldur's Gate 3 to Elden Ring, plays great on a Linux gaming PC in 2026.
