I'm building a €1,500 gaming PC with a Ryzen 5 9600X and Radeon RX 9070 XT. In some games, the system should manage around 60 FPS at native 1440p, but I'm wondering whether rendering at a lower internal resolution and upscaling to 4K with FSR would look better. I'll also be playing competitive shooters such as Valorant and Counter-Strike 2, where high frame rates and low latency matter. Is upscaled 4K worth considering, or should I stick with native 1440p and use a higher refresh-rate monitor?

The monitor size and viewing distance matter a lot. A 27-inch 1440p monitor is already quite sharp, while 4K becomes more worthwhile at 32 inches or larger. The RX 9070 XT should handle many games at 4K, but the best settings will vary; use native resolution when performance is already high and enable FSR when you need extra frames.
For Valorant and CS2, I’d prioritize a high-refresh 1440p display and very high frame rates. Those games are relatively easy to run, so you may be able to play at native 1440p with hundreds of frames per second. For demanding single-player games, you can use FSR Quality at 1440p or try 4K upscaling if your monitor is actually 4K.
Upscaling isn’t creating detail from nowhere, but modern reconstruction is often better than the blurry TAA forced by many games. If a game supports a good native-resolution option such as FSR Native AA, that can be ideal. Otherwise, compare native 1440p with FSR Quality at 1440p or 4K and choose based on image stability, ghosting, and performance.
It depends heavily on the game and monitor, but well-implemented upscaling can look surprisingly good. 4K with FSR in Quality or Balanced mode often looks sharper than native 1440p because it gives the reconstruction algorithm more output pixels to work with. However, FSR quality varies between games, so it isn’t guaranteed to beat native resolution every time.
