As sales events like Amazon Prime Day and Black Friday roll around, the tradition of building a high-performance PC using only discounted components continues. This October 2026 iteration, dubbed the Eurogamer Prime Day PC, focuses on delivering exceptional gaming value, particularly for 1440p resolutions with ray tracing capabilities, for a total cost of £1788.
Core Components
The foundation of this build is the AMD Ryzen 7 7800X3D CPU, a standout choice for gaming workloads. This 8-core, 16-thread processor leverages AMD's 3D V-Cache technology to deliver gaming performance that rivals or surpasses higher-end chips, while still maintaining respectable content creation capabilities. Its AM5 platform also ensures future upgrade paths.
Paired with the CPU is the Asus Prime RX 9070 XT GPU. This graphics card represents a significant leap over previous generations, offering performance that competes with AMD's RX 7900 XT and XTX, and even approaches Nvidia's RTX 5080 in certain benchmarks at 1440p. Its ray tracing performance is also notably improved. The card supports AMD's FSR4 upscaling technology and benefits from recent driver updates enhancing frame generation and ray reconstruction.
For storage, the Netac NV7000-t 2TB NVMe SSD provides a balance of speed and capacity. While not the absolute fastest PCIe 4.0 drive, its sequential read/write speeds of up to 7300MB/s and 6700MB/s respectively, along with strong random IOPS, are more than sufficient for demanding PC and PS5 gaming. The 2TB capacity offers ample space for a significant game library.
Memory is handled by a Crucial Pro 32GB DDR5-6000 CL36 kit. Higher speed DDR5 RAM has shown performance benefits in titles like Cyberpunk 2077 and Flight Simulator 2020. This kit not only offers substantial capacity but also tighter timings suitable for overclocking, providing an additional performance edge.
Supporting Components and Case
The Gigabyte B850 Eagle Wifi 6E motherboard serves as the system's central hub. This ATX board features PCIe 5.0 support for the GPU, three M.2 slots (one Gen 5), and DDR5 RAM support up to 8200MT/s. Connectivity is robust, including Wi-Fi 6E, Gigabit Ethernet, USB-C, and multiple USB-A ports.
A Corsair RM850e (2025) power supply provides ample power for the components and future upgrades. Its 850W capacity exceeds the recommendations for both the RX 9070 XT and the 7800X3D, and it fully complies with ATX 3.1 and PCIe 5.1 standards, including the 12V-2x6 connector. The fully modular design and Gold-rated efficiency contribute to a clean and reliable build.
Cooling for the Ryzen 7 7800X3D is managed by the Thermalright Peerless Assassin 120 SE, a capable dual-tower air cooler that offers effective thermal dissipation for CPUs with moderate TDPs. Its dual 120mm fans and six heatpipes provide performance comparable to more expensive options.
Arctic P12 fans are included as an optional addition for enhanced airflow, offering a cost-effective way to fill additional fan slots in the case.
The NZXT H5 Flow (2024) case is chosen for its ease of building, ample cable routing space, and good airflow design. It supports various radiator sizes and comes with two pre-installed fans, with additional fan mounts available for further cooling customization. Its magnetically attached panels offer convenient access and dust management.
Performance and Value
The completed PC represents a well-rounded system for 1440p gaming, featuring a potent CPU and GPU combination, fast storage, and ample RAM. The selection of components, particularly the AM5 platform and the high-wattage power supply, provides significant room for future upgrades. The total cost of £1788 reflects the current market prices for these components, with the value primarily derived from the strategic acquisition of discounted parts during the Prime Day sale.
