The RX 7800 XT is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply

CPU 253 W + GPU 263 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 616 W. We recommend a 850 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.
