Simulation Gaming PC Build — Best Parts & Tips 2025

Tired of choppy frame rates when you’re lining up the perfect overtake at Kyalami? Or stuttering visuals as you approach O.R. Tambo in a fully loaded A320? A generic gaming PC often struggles with the unique demands of simulation titles. Building the perfect simulation gaming PC build isn’t just about chasing the highest numbers… it’s about crafting a stable, immersive experience where the hardware disappears, leaving only you and the virtual world. Let's get it sorted.

Why a Sim PC Build is a Different Beast

Unlike many fast-paced shooters that rely heavily on the graphics card (GPU), simulation games are often brutal on the processor (CPU). Think about it: titles like Microsoft Flight Simulator, DCS World, or Assetto Corsa Competizione are constantly calculating complex physics, aerodynamics, AI behaviour, and vast environmental data. This makes the CPU the true heart of any serious simulation gaming PC build.

A balanced machine is key, but understanding where to allocate your budget is crucial. Your PC is the central brain powering your entire setup, from your high-refresh-rate monitor to your force-feedback wheel or flight yoke. Getting the core components right ensures every input feels instant and every visual is buttery smooth.

Nailing the Components for Your Sim Rig 🔧

Crafting the best setup for sim games means focusing on components that deliver sustained performance. Here’s a breakdown of what truly matters.

The CPU: The Brains of the Operation

The CPU handles the simulation itself. For years, sim titles favoured high clock speeds on a single core. While that's still important, modern sims are getting better at using multiple cores. A processor with strong single-thread performance and a healthy core count (6 to 8 cores is a fantastic sweet spot) will prevent bottlenecks and keep your physics calculations running smoothly, even in a crowded race or a complex flight plan. A solid CPU is the foundation of many of our best gaming PC deals.

The GPU: Your Window to Another World

Your Graphics Processing Unit (GPU) renders the world you see. For a single 1080p monitor, a mid-range card will serve you well. But the real magic of sim gaming comes with immersive displays. Are you planning a triple-monitor setup for maximum peripheral vision, or strapping on a high-resolution VR headset like the HP Reverb G2? If so, you'll need a powerful GPU to push all those pixels without dropping frames. A high, stable frame rate is non-negotiable for a smooth experience. For these demanding setups, exploring powerful PCs above R20k is a great place to start.

RAM & Storage: The Unsung Heroes

Sims love RAM. With massive, detailed maps and complex aircraft or vehicle models, 16GB is the absolute minimum today. For a truly comfortable experience in titles like MSFS 2020, 32GB is the recommended sweet spot to eliminate stutters.

Equally important is storage. Modern sims can be huge, often exceeding 100GB. A fast NVMe SSD won't just speed up your PC's boot time; it will dramatically cut down on loading screens, getting you onto the track or into the cockpit faster. ✨

TIP FOR YOU

Sim Storage Pro Tip ⚡

games and their add-ons can consume hundreds of gigabytes. Consider a two-drive solution: a primary 1TB NVMe SSD for your operating system and favourite sims, and a larger, more affordable SATA SSD for your less-played titles and scenery packs. This keeps everything running fast without breaking the bank.

Your Perfect Simulation Setup, No Matter Your Budget

A top-tier sim rig is an investment, but you don't need to spend a fortune to get a fantastic experience. The best setup for sim games is the one that matches your goals and your wallet.

The Entry-Level Simmer

Getting started in the world of sim racing or flight sims is more accessible than ever. A modern PC with a capable 6-core CPU and a solid graphics card can deliver an excellent 1080p experience in titles like Euro Truck Simulator 2, Assetto Corsa, or X-Plane 11. You can find some excellent starting points in our range of budget gaming PCs. There are plenty of powerful and affordable options available, with many of the best PCs under R20k offering a perfect gateway into serious simulation.
