Question 2 questions: compatibility? / DDR4 or 5?

[TiluChris]

Hello All

I'm soon building a new computer. I have two questions:
1. Are the below listed components compatible ? I'm a bit unsecured due to all what has changed over the last 6 to 8 years.
2. With those, do I have to put DDR5 or can I stay with DDR4?

Thanks in advance.

If I swap to AMD config, will that below do the job (note: I try to take it white color):
- AMD Ryzen 7 7800X3D
- MSI RTX4080 GAMING X SLIM WHITE
- Gigabyte B650E A Elite X ICE

A 7900xtx would be a bit faster, unless using RT, for same cost as that 4080, and comes packed with 24gb V-ram instead of only 16gb.

And you can get one in white.
