Ryzen 7 7800X3D vs Ryzen 9 7900X3D for Multitasking/3D Printing-Slicing

I've sorted my RAM issue but now I'm lost with processors.

I'm not really gaming a lot on my PC. I'm doing 3D printing and 3D slicing plus have lots of tabs open at same time in few browsers.

All tests/videos I've seen 7 7800X3D being a beast for Gaming with higher FPS due to 3D cache etc but Ryzen 9 have more cores but only half used same way and this one is apparently better for non gaming needs. Price of both is almost same for me but unsure which one would be better. Can anyone advise?
