BOTTLENECK PAIR · GAMING · 1440P HEADLINE
Intel Core i9-13900K + Intel Arc A770
// VERDICT · 1440P GAMING
15% GPU-bound. The Intel Arc A770 is holding back the Intel Core i9-13900K.
GPU is the limiting factor at 1440p gaming. CPU has roughly 15% of headroom available.
TL;DRThe Intel Core i9-13900K + Intel Arc A770 pairing is rated Grade A for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 13% GPU-bound, 1440p: 15% GPU-bound, 4K: 16% GPU-bound. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.

// WHAT THIS PAIRING MEANS FOR YOUR GAMING
Plain-English breakdown.
The Intel Core i9-13900K + Intel Arc A770 pair is 15% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades high-end (A).
Expect around 312 FPS in League of Legends and ~103 in the more demanding Baldur's Gate 3 — both at 1440p with high or ultra presets. Resolution matters more than most calculators show — the same parts give different verdicts at 1080p, 1440p, and 4K because GPU work scales with pixel count while CPU work is roughly fixed per frame.
If you upgrade the gpu, the NVIDIA GeForce RTX 4070 is the closest higher-tier option — see the swap recommendations below for the FPS lift. Plan on at least a 650W PSU — that includes headroom for transient spikes on the Intel Arc A770.
