Based on German prices as you're likely EU.
You don't need an X3D unless you're targetting 240 Hz with a RTX 4090 or better, or play very specific games.
For the price of just the 9800X3D you can get a good 14 core CPU on current platform, motherboard, and cooler.
If you have more money, get 2x32 GB instead and the 1000 W version of the same PSU.
If you have less money, get a 12400F based platform instead with DDR4, won't notice a difference in 120 Hz gaming.
I would advise against any GPU pre RDNA 4, as the upscalers suck and they essentially can't do ray tracing, which is the standard since around 2024 for new AAA games. Doom Dark Ages, Indiana Jones etc, you can't disable it. I doubt GTA6 will differ much.
