The purpose of Step 2
if you have not read Step 1, please refer to our previous blog post: Step 1: How to choose PC parts the right way
“The smartest build isn’t the most expensive. It’s the one with no bottlenecks.”
— Radium PCs
You’ve learned why each part matters, let’s talk about what to actually put in your new Radium PC.
The goal isn’t to chase expensive specs.
It’s to build a system that’s balanced, reliable and gives you the most performance for your budget.
Ground Rules:
-
All builds assume proper airflow, 32GB memory, and an NVMe SSD.
-
We ignore RGB or cosmetic upgrades, this is about raw performance.
- Prices reflect typical Australian availability (as of October 2025).
Radium PCs Workstation precision series, focusing raw performance

3. Australia-specific value insights
- Local pricing matters. NVIDIA and AMD pricing is different in Australia versus the USA, so when comparing systems, keep in mind shipping, duties and fees.
- Ryzen 9800X3D is the no-regrets CPU. Still unbeatable for pure gaming.
-
GPU choice drives performance. If a 5070 is within ~$150 of a 5060 Ti 16 GB in your Radium PCs customer builder, the 5070 is always worth it.
4. Building your Radium PCs smart, not big
PC performance scales with balance — not budget.
The smartest builds come from understanding component hierarchy and letting each part play its role.
At Radium, every system is tuned around that principle:
- No bottlenecks
- No mismatched components
- Every rig thermally validated and benchmark-checked before it ships.

Final Word
The best gaming PC in 2025 isn’t about chasing numbers, it’s about control, thermals, and reliability.
Understand why you choose each part, and what delivers the best value for your budget.
That’s how Radium builds.
That’s how you win.
FAQ Section
Q: Is the Ryzen 7800X3D still the best gaming CPU in 2025?
A: Yes. Tt delivers near-top performance at a lower price than the 9800X3D.
Q: What GPU is best for 1440p gaming?
A: The RTX 5070 or 5070 Ti balance cost and longevity for Aussie gamers.
Q: Is Intel or AMD better for gaming right now?
A: Both perform well, but AMD’s X3D CPUs lead in pure gaming efficiency. Intel’s latest chips still win in certain mixed workloads or heavy creation tasks.
Q: How much RAM and storage should a modern gaming PC have?
A: 32 GB DDR5 and a 1–2 TB NVMe SSD hit the current sweet spot. More than that is only worthwhile for creators or massive game libraries.
