How many FPS do AMD Ryzen 7 9850X3D and AMD RX 9070 XT manage in Counter-Strike 2 at 1440p and high settings?
An estimated 300 FPS in Counter-Strike 2 at 1440p and high settings. In more demanding titles such as Cyberpunk 2077 it is closer to 156 FPS. Both are model calculations, not measurements.
Is the AMD Ryzen 7 9850X3D + AMD RX 9070 XT 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 (49 % apart), which is why the frame rate stays steady in busy scenes. There is no reason to upgrade. At around 300 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 5080. Concrete suggestions with price and cost per FPS come from the buying advice in the Performance Hub.
