1. Establish Your Requirements
Before you compare any specifications, you need to set clear targets.
First, determine your budget. This will guide every other decision. Entry-level gaming systems in Australia typically start around AUD $1,200–$1,500, mid-range builds fall in the $2,000–$2,800 range, and high-end configurations exceed $3,500.
Next, decide on your target resolution and refresh rate:
- 1080p / 60–144Hz – Less expensive hardware; ideal for competitive play or older titles.
- 1440p / 144Hz – The balance point for sharp visuals and smooth frame rates.
- 4K / 120Hz+ – Demands high-end GPUs and strong CPUs; suitable for premium setups.
Finally, identify the primary game types you play.
Fast-paced esports titles prioritise frame rate and responsiveness. AAA games benefit from higher visual settings and GPU performance. Simulation or VR workloads require both CPU and GPU capacity. If you plan to stream, edit video, or use productivity applications, you’ll also need more RAM and storage.
2. Selecting Components
CPU (Processor)
The CPU executes game logic, physics, and background system tasks.
- Mid-range recommendations: Intel Core i5-13400F, AMD Ryzen 5 7600.
- High-end recommendations: Intel Core i7-13700K, AMD Ryzen 7 7800X3D (optimal for gaming workloads).
Avoid purchasing the most expensive CPU available if you are not also pairing it with a high-end GPU.
GPU (Graphics Card)
The GPU determines the majority of your in-game frame rate and graphical quality.
- 1080p: NVIDIA RTX 4060, AMD RX 7600.
- 1440p: NVIDIA RTX 4070 / 4070 Super, AMD RX 7800 XT.
- 4K: NVIDIA RTX 4080 / 4080 Super, AMD RX 7900 XTX.
When choosing, review benchmarks for your target games at your intended resolution and refresh rate.
RAM (Memory)
RAM stores active game and application data for quick access.
- Minimum: 16GB (DDR4-3200 or DDR5-5600).
- Preferred: 32GB for future-proofing, streaming, or multitasking.
Ensure your motherboard supports the chosen RAM type and speed.
Storage
An NVMe SSD significantly reduces load times compared to SATA SSDs or HDDs.
- Recommended primary drive: 1TB NVMe SSD (PCIe Gen 3 or Gen 4).
- Optional: Secondary 2TB–4TB HDD for large libraries or media storage.
Motherboard
Select one compatible with your CPU socket and chipset.
Consider:
- Number of PCIe slots
- RAM speed support
- Networking options (Wi-Fi or Ethernet)
- USB and storage connectivity
- BIOS features for updates and overclocking
Power Supply (PSU)
A reliable PSU ensures stable power delivery and system safety.
- Wattage: 650W–850W for most gaming PCs.
- Efficiency rating: 80+ Gold or better.
Choose from reputable brands such as Corsair, Seasonic, or EVGA.
Cooling
Adequate cooling maintains performance and prolongs component lifespan.
- Stock air coolers are sufficient for non-overclocked CPUs.
- High-performance CPUs or overclocked systems benefit from aftermarket air coolers or liquid cooling solutions.
Case
The case must fit your chosen components.
- Check GPU length, CPU cooler height, and PSU clearance.
- Ensure sufficient airflow with front, top, and rear ventilation.
- Consider cable management options and dust filtration.
3. Decide How to Acquire the System
You have three practical options:
- Prebuilt System – Ready to use out of the box, tested, and covered by warranty. Often less flexible with part choices, may include cost markups.
- Custom-Built by Retailer – You choose each component; the retailer assembles and tests it. More control, but higher assembly cost.
- DIY Assembly – You buy each component and assemble it yourself. Lowest potential cost, maximum control, but requires technical skill and time.
4. Purchasing Guidelines
- Avoid mismatched CPU/GPU performance levels to prevent bottlenecks.
- Check independent benchmarks for your preferred games.
- Allow for future upgrades by selecting a PSU with headroom and a case with expansion capacity.
- Monitor sales events (EOFY, Boxing Day, Black Friday) for lower prices.
- Avoid unnecessary spending on cosmetic features if performance is the priority.
