I'm stuck with DDR5 5600MHz CL40 RAM because of availability, while I keep hearing that 6000MHz CL30 is the sweet spot for performance. Given my setup with an RTX 3800Ti and Ryzen 7 9800x3D, how does this impact gaming performance at 1440p? Should I be worried about losing a lot of performance due to my RAM choice?

You're looking at a difference of about 5-10% in performance depending on the game. The Ryzen 7 9800x3D has a larger L3 cache, which helps it do more work without constantly relying on RAM, so you probably won’t feel that gap as much. Honestly, if you hit above 60 FPS in your games, you should be happy!

That sounds good to me, especially since I was getting around 45 FPS before. As long as I can maintain 60 FPS in Space Marine 2, I’ll be content!
