I finally assembled a high-end workstation (for home use). Initially, I got a white 5080, but it didn't have enough memory for neural networks, so:
Ryzen 9 9950x
Palit rtx 5090
IRDM 64 gram
MSI x670e
be quiet dark power pro 1300w
1tb samsung 990 pro
1tb nv2 Kingston
256 cache 970 evo plus
be quiet silent loop 2
silent base 802
I was very upset when I found out that there is also an RTX 6000 Pro, but at the moment it is clearly beyond my budget😥
