This build is designed specifically for 1440p DOOM (2016) by delivering enough GPU rasterization power and VRAM to keep particle effects, dynamic lighting, and high-resolution shadows running smoothly without stuttering during horde encounters. It accepts a moderate overall budget by using efficient current-generation parts that match the game's optimization level instead of chasing flagship components the engine cannot fully utilize. The result is a system that stays responsive through the campaign's most intense arenas while leaving headroom for SnapMap experiments or occasional multiplayer. The Ryzen 9 7900X provides 12 cores and 24 threads that comfortably handle the CPU spikes caused by enemy AI, physics, and simulation when dozens of demons fill a room. Paired with the SAPPHIRE Radeon RX 9060 XT PULSE 16GB, the balance tilts toward the GPU because 1440p primarily increases pixel workload and VRAM demand rather than raw CPU threading. The 16 GB of GDDR6 ensures textures and effects stay loaded even when settings push shadow and particle quality high, directly addressing the VRAM sensitivity that creates hitches at this resolution. System-wide choices reinforce this focus. The ASUS Prime B650-PLUS WiFi motherboard and 16 GB DDR5-6000 RAM provide a modern, stable platform without excess cost. The Kingston NV3 1 TB NVMe SSD loads the 55 GB install plus any SnapMap content quickly, while the Thermalright Peerless Assassin cooler keeps the 170 W CPU at good temperatures under sustained combat loads. The Montech AIR 903 case supplies strong airflow for the RX 9060 XT, and the 650 W MSI PSU meets power requirements with margin for stability. Together these parts avoid common mismatches by giving the GPU the VRAM headroom it needs at 1440p and the CPU the core count required for stable minimum frame times, creating a coherent system built for the exact demands of fast, particle-heavy demon-slaying.
