How many FPS do Intel Core i5-13400 and AMD RX 5700 XT manage in Counter-Strike 2 at 1440p and high settings?
An estimated 110 FPS in Counter-Strike 2 at 1440p and high settings. In more demanding titles such as Cyberpunk 2077 it is closer to 57 FPS. Both are model calculations, not measurements.
Is the Intel Core i5-13400 + AMD RX 5700 XT combination enough for 1440p?
For 1440p this combination sits at the entry level. In demanding games you will need to reduce detail or use upscaling such as DLSS or FSR. 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 (71 % apart), which is why the frame rate stays steady in busy scenes. There is no reason to upgrade. At around 110 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 2070 Super. Concrete suggestions with price and cost per FPS come from the buying advice in the Performance Hub.
