How many FPS do Intel Core i9-13900K and AMD RX 7900 GRE manage in Counter-Strike 2 at 1440p and high settings?
An estimated 252 FPS in Counter-Strike 2 at 1440p and high settings. In more demanding titles such as Cyberpunk 2077 it is closer to 131 FPS. Both are model calculations, not measurements.
Is the Intel Core i9-13900K + AMD RX 7900 GRE combination enough for 1440p?
By the model, yes: for 1440p at high settings the combination is a good fit. Balanced for 1440p. The graphics card is the narrower side, and at this resolution that is how it should be: more pixels load the card, not the processor. Your processor keeps headroom (55 % apart), which is why the frame rate stays steady in busy scenes. There is no reason to upgrade. At around 252 frames, more power no longer changes the band you play in.

Is an upgrade worth it?
The next step that makes sense by the model would be NVIDIA RTX 5070. Concrete suggestions with price and cost per FPS come from the buying advice in the Performance Hub.
