Core Ultra 5 245K + RTX 3070: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The RTX 3070 is the part working hardest at 1440p, which is what you want. The Core Ultra 5 245K keeps about 21% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 14% | balanced |
| 1440p | GPU | 21% | GPU-bound (normal) |
| 4K | GPU | 39% | GPU-bound (normal) |
The RTX 3070 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 159 W + GPU 220 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 479 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.
