Ryzen 7 3700X + RX 6600: 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 | 10% | balanced |
| 1440p | CPU | 1% | balanced |
| 4K | GPU | 22% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Ryzen 7 3700X is the limit (10%), while at 4K the RX 6600 takes over (22% 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 RX 6600 measured 120 W average while gaming (249 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 3700X at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 260 W. A 450 W unit is the safe choice.
