Ryzen 9 5950X + RTX 3080: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 3080 is the slightly busier part, by about 4%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 4% | balanced |
| 1440p | GPU | 4% | balanced |
| 4K | GPU | 25% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Ryzen 9 5950X is the limit (4%), while at 4K the RTX 3080 takes over (25% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply
The RTX 3080 measured 336 W average while gaming (422 W highest 20 ms spike, TechPowerUp). With the Ryzen 9 5950X at its TDP of 105 W and about 75 W for the rest of the system, the sustained load is about 516 W. A 750 W unit is the safe choice.
