Early next week I will complete the build of 32core 2990WX for Veronika and then slap on some heavy GPU, either 1080ti which can now be bought for 500 Euros, or maybe wait for the overpriced 2080/2080ti. I am really interested how fast will this make previews with the nVidia Optix denoiser during interactive, I have high hopes it will be quite responsive.
Anyway, 10GBE is great improvement for other workstations tasks, like saving 3dsMax scenes onto fileserver, loading assets from Connecter, multiple users accessing the fileserver. If you have filserver with SSDs, 10GBE is absolute must.
I didn't answer the last question, but the Asus (Made by Aquantia) is fine card as long as you adjust one setting which I never remember from head (Under IP6 settings). The Intel is superior though, but you need to order it from China to get good price.
