This 1440p DOOM Eternal PC build puts the RX 9060 XT 16GB at the center of the system. With 16GB of dedicated video memory, the graphics card has the headroom to handle high-resolution textures and particle-heavy scenes without the VRAM choking that catches some players off guard at 1440p. This is the component doing the heavy lifting during every arena fight. The AMD Ryzen 9 7900X gives the system a strong CPU foundation. While DOOM Eternal's id Tech 7 engine leans heavily on the GPU, the Ryzen 9 7900X ensures clean frame pacing and leaves plenty of overhead for background tasks, streaming, or modded content that can add extra CPU load. Paired with 16GB of DDR5-6000 RAM from Patriot, the memory subsystem stays fast enough to keep up with the engine's efficient resource handling. The Kingston NV3 1TB NVMe SSD handles the game's texture streaming without the pop-in issues that plague slower drives. DOOM Eternal streams assets aggressively during gameplay, and an NVMe SSD keeps that pipeline smooth throughout each level. The 650W MSI MAG power supply gives the system a reliable foundation without overspending on wattage you will not use at this performance tier. The Montech AIR 903 case keeps thermals manageable with good airflow, and the Peerless Assassin 120 SE cooler keeps the 7900X temperatures in check without adding unnecessary cost. Together, this build prioritizes the GPU performance 1440p demands while keeping every supporting component at a level that avoids bottlenecks — a balanced approach that matches DOOM Eternal's GPU-driven design at this resolution.
