This is the classic pattern: at 1080p the Core i5-13400F is the limit (4%), while at 4K the RX 6900 XT takes over (25% 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 6900 XT measured 305 W average while gaming (636 W highest 20 ms spike, TechPowerUp). With the Core i5-13400F at its maximum turbo power of 148 W and about 75 W for the rest of the system, the sustained load is about 528 W. A 1000 W unit is the safe choice.
