Ryzen 7 9700X + RTX 4080 Super: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 4080 Super is the slightly busier part, by about 4%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 3% | balanced |
| 1440p | GPU | 4% | balanced |
| 4K | GPU | 24% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Ryzen 7 9700X is the limit (3%), while at 4K the RTX 4080 Super takes over (24% 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 4080 Super measured 302 W average while gaming (341 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 9700X at its TDP of 65 W and about 75 W for the rest of the system, the sustained load is about 442 W. A 750 W unit is the safe choice.
