Why This Build for Baldur's Gate 3
Even at $1800, Baldur's Gate 3 returns 105 FPS on Ultra at 1440p — 15 short of 120 Hz. That is what this engine costs: 60 Hz native on the RX 7800 XT, 120 Hz once Cloud Quality gives or the upscaler does.
Above the RX 7800 XT sits the RTX 5070 TI, worth 142 FPS in Baldur's Gate 3 at 1440p: 37 frames, roughly 35%. That is the card that takes Baldur's Gate 3 over 120 Hz, which is the honest reason to want it. Street pricing settles that one. The $850 ceiling is what keeps $1800 balanced rather than a Baldur's Gate 3 GPU bolted to a starved platform.
Divinity 4.0 keeps every NPC, spell surface and stacked status effect inside a turn-resolution simulation, so this game gets heavier as your save gets older rather than as the scenery gets prettier — Act 3's Lower City is where frame rate falls off a cliff, and it falls on the CPU while GPU load barely moves from what Act 1 asked for. Because Baldur's Gate 3 is CPU-bound, $1800 is better tilted toward the AMD Ryzen 7 7700 than a generic build at this price would be. A card past the RX 7800 XT waits on frames the processor has not finished.
Measured across resolutions, the RX 7800 XT in Baldur's Gate 3 reads — 1080p: 130 FPS, on Ultra, asking about 6 GB; 1440p: 105 FPS, on Ultra, asking about 7 GB; 4K: 60 FPS, on High, asking about 9 GB. Quoted at 1440p for $1800. The step to the next rung is where Baldur's Gate 3 stops being free and Cloud Quality becomes the question.
Baldur's Gate 3 on Ultra at 1440p calls for something like 7 GB of video memory, against 16 GB on the RX 7800 XT — 9 GB spare, enough that Baldur's Gate 3 textures are not a decision a $1800 buyer has to make.
Baldur's Gate 3 ships DLSS and FSR. Even at $1800, DLSS on Quality is what carries Baldur's Gate 3 to 120 Hz; Cloud Quality is the second resort.
