Ryzen 5 5600X + RTX 3070: bottleneck check
Evenly matched at 1440p.
Neither part waits on the other at 1440p. This is as balanced as a pairing gets.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 7% | balanced |
| 1440p | GPU | 2% | balanced |
| 4K | GPU | 24% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Ryzen 5 5600X is the limit (7%), while at 4K the RTX 3070 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 3070 measured 232 W average while gaming (283 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 5600X at its TDP of 65 W and about 75 W for the rest of the system, the sustained load is about 372 W. A 650 W unit is the safe choice.
