This is the classic pattern: at 1080p the Ryzen 7 5700X3D is the limit (5%), while at 4K the RX 9070 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 RX 9070 measured 233 W average while gaming (283 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 5700X3D at a power figure of 105 W and about 75 W for the rest of the system, the sustained load is about 413 W. A 650 W unit is the safe choice.
