I'm think ong upgrading to a full new PC from Ryzen 9 3900X + RX 5700 XT.

Was initially thinking on just buying a RX 9070 XT and be done with it but now I'm considering just buying everything new. It's mainly for gaming on a ultrawide 4k monitor with a second monitor on the side.
This is the build I was thinking: https://pt.pcpartpicker.com/list/yYDHW9 (not sure why it says the PSU is not compatible with the case, since the case spec says it is compatible).

My question is if I should go for the Ryzen 7 7800X3D or 9800X3D or even a different CPU. 60€ difference in price in my local store. Any advise is appreciated
