Best $1800 PC Build for Call of Duty: Warzone (2026)

Even at $1800, Call of Duty: Warzone returns 110 FPS on Balanced at 1440p — 130 short of 240 Hz. That is what this engine costs: 60 Hz native on the RX 7800 XT, 240 Hz once Shadow Map Resolution gives or the upscaler does.

Above the RX 7800 XT sits the RX 7900 XTX, worth 145 FPS in Call of Duty: Warzone at 1440p: 35 frames, roughly 32%. Street pricing settles that one. The $850 ceiling is what keeps $1800 balanced rather than a Call of Duty: Warzone GPU bolted to a starved platform.

Warzone streams a battle-royale map at texture resolutions high enough to make VRAM the first wall you hit, which is GPU-and-memory work — but the settings the game is balanced around are the reduced ones competitive players run for 200+ FPS, and past roughly 160 FPS the cost of tracking a hundred-plus players and their spatialised audio moves the ceiling onto the CPU. With Call of Duty: Warzone splitting load between the AMD Ryzen 7 7700 and the RX 7800 XT, $1800 is where balance stops costing anything: both halves clear the point where either is the obvious bottleneck at 240 Hz.

Measured across resolutions, the RX 7800 XT in Call of Duty: Warzone reads — 1080p: 140 FPS, on Balanced, asking about 8 GB; 1440p: 110 FPS, on Balanced, asking about 10 GB; 4K: 70 FPS, on Balanced, textures Normal, asking about 14 GB. Quoted at 1440p for $1800. The step to the next rung is where Call of Duty: Warzone stops being free and Shadow Map Resolution becomes the question.

Call of Duty: Warzone on Balanced at 1440p calls for something like 10 GB of video memory, against 16 GB on the RX 7800 XT — 6 GB spare, enough that Call of Duty: Warzone textures are not a decision a $1800 buyer has to make.

Call of Duty: Warzone ships DLSS, FSR and XeSS. Even at $1800, DLSS on Quality is what carries Call of Duty: Warzone to 240 Hz; Shadow Map Resolution is the second resort.
