Ryzen 9 5950X + GTX 1080 Ti: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The GTX 1080 Ti is the part working hardest at 1440p, which is what you want. The Ryzen 9 5950X keeps about 21% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 13% | balanced |
| 1440p | GPU | 21% | GPU-bound (normal) |
| 4K | GPU | 39% | GPU-bound (normal) |
The GTX 1080 Ti is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.
