Best Sim Racing Setup for Beginners: Start With the Essentials
You don’t need a full cockpit immediately. A well‑chosen beginner setup helps you develop skills faster and keeps costs under control.
1. Steering Wheel and Pedals (Top Priority)
Your wheel and pedals are the most important part of any sim racing rig. Force feedback allows you to feel grip changes, kerbs, and steering resistance—crucial for learning car control.
Beginner tip: Focus on force feedback quality rather than raw power.

The point is don't buy a £150 mouse expecting it to fix your aim. Buy it because the weight, shape, and quality will make long gaming sessions more comfortable.
AWD-IT stocks gaming mice from Razer, Corsair, and ASUS at a range of price points. If you're unsure where to start, a mid-range wireless mouse from any of these brands will give you everything you need for competitive gaming.
Signs your PC has genuinely run its race
When It IS Time for a Full Rebuild
Even Messi will retire eventually. And there are signs your PC has genuinely run its race:
• CPU is pre-2018 and DDR3 (no DDR5 upgrade path available)
• Motherboard doesn't support PCIe 4.0 — you're bottlenecking modern GPUs
• Power supply is under 500W — can't safely run anything modern
• Multiple components failing, temperatures consistently hitting 90°C+
If you're ticking more than two of those boxes, a fresh AWD-IT pre-built is often better value than stacking upgrades onto a dead-end platform. You get a warranty, a coherent spec, and you know everything works together from day one.
Frequently Asked Questions
Is the Ryzen 7 5700X3D good enough for the RTX 5070?
Yes. It's one of the best-value CPUs available for gamers already using the AM4 platform.
Should I choose AMD or Intel?
Both platforms offer excellent gaming performance. AMD currently has an advantage in gaming thanks to its X3D processors, while Intel remains a strong choice for users who combine gaming with productivity.
Is DDR5 worth upgrading to?
If you're building a new PC, yes. DDR5 provides better performance and a longer upgrade path.
Final Verdict
The RTX 5070 is an outstanding graphics card, but pairing it with the right CPU is essential to unlocking its full potential.
For new builds, the Ryzen 7 7800X3D remains the ultimate gaming processor. Existing AM4 users can save money by upgrading to the Ryzen 7 5700X3D without sacrificing excellent gaming performance.
Whichever route you choose, combining the RTX 5070 with fast memory, an NVMe SSD and a quality power supply will provide a gaming experience capable of handling today's biggest titles for years to come.
