Ryzen 9 7950X3D + RX 6600: bottleneck check
GPU-limited at 1440p. CPU overkill.
The RX 6600 is the part working hardest at 1440p, which is what you want. The Ryzen 9 7950X3D keeps about 42% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 36% | GPU-bound (normal) |
| 1440p | GPU | 42% | CPU overkill |
| 4K | GPU | 55% | CPU overkill |
The RX 6600 is the limit at every resolution and by a wide margin at 4K (55%). The Ryzen 9 7950X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply
CPU 120 W + GPU 132 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 352 W. We recommend a 550 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.
