I'm building my first gaming PC in Australia with a budget of about $2,500 AUD for the tower only. I already have older peripherals and will replace them gradually. I'd like the system to last roughly five to seven years, while keeping the option to upgrade the graphics card later.
I'm willing to use a mid-range or second-hand GPU initially so I can spend more on reliable, high-quality components that will remain useful over time. I also want to avoid paying extra for features that provide little real-world gaming benefit. Advice on dependable brands and good-value models for the CPU, motherboard, memory, storage, power supply, case, and cooling would be helpful.
The parts I've been considering include a Ryzen 7 9800X3D, Radeon RX 9070 XT, 32GB of DDR5-6000 CL30 or CL32 memory, an 850W 80+ Gold fully modular PSU, and an MSI B850 Gaming Plus WiFi motherboard. Is a Noctua air cooler worth the premium, or are there cheaper coolers with similar performance and quality?
I'd also like to understand how noticeable the difference is between gaming at 1440p and 4K, since I haven't chosen a monitor yet. Finally, what Australian retailers or deal-finding websites are good places to compare prices on components?

The choice between 1440p and 4K should start with the monitor you want. At normal desk distances, 4K looks sharper, especially on larger screens, but 1440p is still very clear and is substantially easier for the GPU to run at high settings and high refresh rates. A strong 1440p setup often gives a smoother experience and better value, while 4K makes more sense if you specifically want maximum image sharpness and accept lower frame rates or the need for upscaling.
For a long-term build, AM5 is the sensible platform because it leaves you more room for future CPU upgrades. Before buying, put every part into a compatibility checker so you can confirm socket support, memory clearance, case dimensions, and power requirements. Don’t choose parts based only on brand; compare the specific model’s warranty, reviews, thermals, and price.
You probably don’t need to spend the whole budget on a 9800X3D unless you’re targeting very high frame rates with a powerful graphics card. A slightly cheaper X3D processor could free up money for a 1TB or 2TB NVMe SSD, since storage is missing from the proposed parts list. For gaming, 32GB of DDR5-6000 with decent timings is a good starting point, and an 850W Gold PSU gives useful headroom for a future GPU upgrade.
A Thermalright Peerless Assassin or Phantom Spirit is usually much cheaper than a Noctua cooler while delivering very similar gaming temperatures. Noctua has excellent build quality and support, but its premium is not usually necessary for this kind of build. Just check that the cooler fits your case and doesn’t interfere with the memory modules.
For Australian pricing, compare several local retailers rather than assuming one store is always cheapest. Deal aggregators can help track CPU, GPU, and complete-system discounts, and second-hand marketplaces may occasionally have worthwhile graphics-card deals. Check the seller’s warranty and return policy carefully, especially for used GPUs, and don’t delay too long if a reputable part reaches a good price because component pricing changes frequently.
The power supply is one component where cutting costs carelessly is a bad idea. Choose a well-reviewed unit from a reputable platform and leave roughly 150–200W of headroom above the system’s estimated maximum draw to help handle transient power spikes.
