Ryzen 9 7950X3D + RTX 5070: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The RTX 5070 is the part working hardest at 1440p, which is what you want. The Ryzen 9 7950X3D keeps about 23% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 16% | balanced |
| 1440p | GPU | 23% | GPU-bound (normal) |
| 4K | GPU | 40% | GPU-bound (normal) |
The RTX 5070 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.

Power supply
CPU 120 W + GPU 250 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 470 W. We recommend a 650 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
