Ryzen 7 5800X3D + RTX 4090 in Baldur's Gate 3

Every figure below is a measurement aggregated from published review charts — the CPU's frame-rate ceiling and the GPU's frame-rate ceiling in this game, combined. Settings: Ultra preset, DX11, native rendering, no upscaling, no frame generation. CPU ceiling measured at 1080p, Medium preset (reviewers' CPU-isolation method), flagship GPU, Act III.

1080p

Strong CPU limit

Expected frame rate: 126–126 fps (measured range across sources).

CPU Ryzen 7 5800X3Dceiling ~126 fps on its own

GPU RTX 4090ceiling ~217 fps on its own

The CPU side is lower by about 42.0%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

1440p

Strong CPU limit

Expected frame rate: 126–126 fps (measured range across sources).

CPU Ryzen 7 5800X3Dceiling ~126 fps on its own

GPU RTX 4090ceiling ~216 fps on its own

The CPU side is lower by about 41.6%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

4K

Mild CPU limit

Expected frame rate: 126–126 fps (measured range across sources).

CPU Ryzen 7 5800X3Dceiling ~126 fps on its own

GPU RTX 4090ceiling ~151–160 fps on its own

The CPU side is lower by about 18.9%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 3 source measurements for these two parts.
