Still have to buy the CPU which will probably be the i9-10900K.
Motherboards to choose: Asus ROG Strix Z490-E Gaming and Asus Z490 ROG Maximus XII Hero Wifi. First one with 50A, the second one with 60A.
I already got an answer that it would be the same. But I don't believe that 2,5 to 10 ethernet and 1 or 2 more ports is sufficient to justify extra 150 euros. So, there should be something different between them.
