This is the classic pattern: at 1080p the Core i7-11700K is the limit (5%), while at 4K the RTX 3070 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

CPU 125 W + GPU 220 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 445 W. We recommend a 650 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
