Core i7-14700K + RX 6600: bottleneck check

39%

GPU-limited at 1440p. GPU-bound (normal).

The RX 6600 is the part working hardest at 1440p, which is what you want. The Core i7-14700K keeps about 39% in reserve.

By resolution

The RX 6600 is the limit at every resolution and by a wide margin at 4K (53%). The Core i7-14700K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

CPU 253 W + GPU 132 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 485 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.
