CAA Budget 4K PC Build – RTX 5080 Gaming PC Under $4,000
A Genuine Budget 4K Gaming PC Without Budget-Level Graphics
Finding a genuine budget 4K gaming PC in Australia can be difficult. Many affordable gaming computers compromise on their graphics cards, limiting performance in demanding games.
The CAA Budget 4K PC Build takes a different approach.
Instead of spending unnecessarily on flagship processors and expensive cosmetic components, we’ve prioritised the NVIDIA GeForce RTX 5080 16GB, delivering the graphics performance that matters most for gaming at 3840 × 2160.
Powered by the AMD Ryzen 5 7500F and ASUS PRIME RTX 5080, this system provides a compelling balance of price, gaming performance and upgradeability.
Real RTX 5080 Performance
The ASUS PRIME GeForce RTX 5080 16GB delivers next-generation NVIDIA Blackwell graphics, advanced ray tracing, DLSS technology and excellent 4K gaming capabilities.
No Unnecessary Flagship CPU Tax
The Ryzen 5 7500F provides six cores, twelve threads and a modern AM5 platform without dramatically increasing the complete PC’s cost.
Standard, Upgradeable Components
Unlike proprietary gaming desktops, this computer uses recognised desktop hardware from ASUS, AMD, Gigabyte, Crucial, PNY, Thermalright, MSI and DeepCool.

AMD Ryzen 5 7500F – Smart Performance for 4K Gaming
The AMD Ryzen 5 7500F is a six-core, twelve-thread processor based on AMD’s modern AM5 architecture.
It provides responsive gaming performance while keeping the cost of the overall system controlled.
At 4K resolution, many graphically demanding games rely heavily on GPU performance, making the Ryzen 5 7500F a practical choice for a budget-focused RTX 5080 gaming PC.
For gamers who want maximum frame rates in CPU-intensive games or high-refresh-rate competitive esports, an upgrade to an AMD Ryzen 7 or compatible Ryzen X3D processor may provide additional performance.
ASUS PRIME RTX 5080 16GB – Powerful 4K Graphics
The centrepiece of this build is the ASUS PRIME NVIDIA GeForce RTX 5080 16GB.
Featuring NVIDIA Blackwell architecture and 16GB GDDR7 video memory, the RTX 5080 is designed for exceptional high-resolution gaming performance.
Key features include:
- 16GB GDDR7 graphics memory
- NVIDIA DLSS and supported frame-generation technology
- Advanced hardware-accelerated ray tracing
- High-performance 1440p and 4K gaming
- NVIDIA Reflex support in compatible games
- GPU acceleration for supported streaming and content-creation applications
The RTX 5080 allows you to prioritise graphical fidelity and high-resolution gaming without purchasing an expensive flagship system.
16GB Crucial DDR5 Memory – Affordable and Upgradeable
The system includes one 16GB Crucial DDR5-5600 CL46 memory module.
This provides a starting point for gaming and everyday applications while leaving an upgrade path to 32GB or more.
For demanding new games, heavy multitasking, streaming or large mod collections, upgrading to 32GB in a dual-channel configuration is recommended.
1TB PNY NVMe SSD – Fast Solid-State Storage
The PNY CS1031 1TB NVMe SSD provides responsive system startup, application loading and game storage.
Using a PCIe 3.0 NVMe interface, this drive offers substantially faster access than conventional mechanical hard drives.
Customers with large gaming libraries can request expanded storage before assembly.
Thermalright ARGB Air Cooling
The AMD Ryzen 5 7500F is cooled by the Thermalright Assassin X Refined SE ARGB.
This tower-style air cooler provides practical CPU cooling with an illuminated fan, offering a balance of thermal performance, reliability and value.
DeepCool CG530 4F – Panoramic RGB Gaming Case
