THE SHORT ANSWER
The AMD Ryzen 5 3600X + NVIDIA GeForce RTX 4070 Ti pairing is rated Grade A for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 11% CPU-bound, 1440p: 7% CPU-bound, 4K: 3% CPU-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.

Plain-English breakdown.
What this pairing actually means when you sit down to play.
The AMD Ryzen 5 3600X + NVIDIA GeForce RTX 4070 Ti pair is 7% CPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades high-end (A).
Expect around 296 FPS in League of Legends and ~82 in the more demanding Starfield — 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 cpu, the AMD Ryzen 5 9600X 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 NVIDIA GeForce RTX 4070 Ti.
The same pair gives a different answer at 1080p, 1440p, and 4K.
Higher resolutions push work onto the GPU — watch the balance shift.

Common questions.
Straight answers for the AMD Ryzen 5 3600X + NVIDIA GeForce RTX 4070 Ti.
Can the AMD Ryzen 5 3600X run the NVIDIA GeForce RTX 4070 Ti?
Yes, the AMD Ryzen 5 3600X will run the NVIDIA GeForce RTX 4070 Ti, but it's the limiting part — at 1440p the pair is 7% CPU-bound, so the AMD Ryzen 5 3600X can't fully feed the NVIDIA GeForce RTX 4070 Ti and you'll leave some frames on the table (most noticeable at 1080p and high-refresh). The swap suggestions below list CPUs that unlock more of the NVIDIA GeForce RTX 4070 Ti.
Will the NVIDIA GeForce RTX 4070 Ti bottleneck the AMD Ryzen 5 3600X?
The AMD Ryzen 5 3600X + NVIDIA GeForce RTX 4070 Ti pairing is rated Grade A for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 11% CPU-bound, 1440p: 7% CPU-bound, 4K: 3% CPU-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 PSU do I need for a AMD Ryzen 5 3600X + NVIDIA GeForce RTX 4070 Ti build?
For a AMD Ryzen 5 3600X (95W TDP) paired with a NVIDIA GeForce RTX 4070 Ti (285W TDP), we recommend a 650W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
