Ryzen 7 3700X + RX 5700 XT: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The Ryzen 7 3700X is the slightly busier part, by about 3%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 12% | mild CPU bottleneck |
| 1440p | CPU | 3% | balanced |
| 4K | GPU | 20% | balanced |
This is the classic pattern: at 1080p the Ryzen 7 3700X is the limit (12%), while at 4K the RX 5700 XT takes over (20% 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 5700 XT measured 215 W average while gaming (266 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 355 W. A 650 W unit is the safe choice.
