Is upgrading from a Ryzen 9 3950X to a 7800X3D worth it for 1440p competitive gaming?

I currently have a PC dedicated to simulation work with a Ryzen 9 3950X and 32GB of 3600MHz CL16 memory. My gaming laptop recently died, so I'm considering using this system for gaming as well. The 3950X looks fairly dated in gaming benchmarks, though.
Would it be worth building a new system around a Ryzen 7 7800X3D, assuming both systems use the same RTX 5060 Ti graphics card? Or would I be better off keeping the current PC and only buying the graphics card? I'm planning to play at 1440p and would like to reach 144 FPS or higher in competitive games.

I’d start by keeping the current system and adding the graphics card. If you’re already getting over 144 FPS in the games you play, a platform upgrade won’t make much practical difference. You can always measure performance first and upgrade later if the CPU is clearly holding you back.

The 7800X3D can provide a substantial gaming improvement in CPU-limited titles, especially competitive games, but the upgrade is expensive. At 1440p, the graphics card will often be the limiting factor, and reaching 144 FPS with an RTX 5060 Ti may require low or medium settings depending on the game.

If you do move to the 7800X3D, remember that you’ll need a new motherboard and DDR5 memory. A 2x16GB kit rated around 6000MT/s with CL30 timings is a sensible pairing. Since productivity performance isn’t important for this particular gaming system, the 7800X3D makes more sense than a newer high-core-count chip.

A cheaper option would be a Ryzen 9 5950X. It’s still a meaningful improvement for gaming while keeping the existing motherboard and memory, and it would preserve much more productivity performance than moving to a 7800X3D.

MellowCedar42: I already have a Ryzen 9 9950X3D, but that system is occupied running Ansys continuously across all cores. I’m not concerned about productivity performance on the gaming machine.
