[Bglug] New computer build recommendations?

[ted leslie]

One could say there is a lot of mobo's that can fit your needs.
In a machine I bought 2 years ago, I wanted decent card slot capabilities
for good nvidia cards.
I got 128 GB of ram, and run kvm on host, and many linux and windows etc as
guests.
There is one HUGE problem if you go kvm (or any other virt), which is PCI
passthrough.
I didn't realize it at the time, but just because you have 2-3 high channel
slots, doesn't mean
you can properly put in 2-3 pci video cards and expect a good segmenting of
the mobo. for virt.
The diff. mobo makes and models segment the buses differently, so you can
get a
mobo that makes a good 2-3 video cards kvm host with segmented guests, or
another
powerful mobo, will have a bad assignment, and it will sux for kvm
pci-passthrough.
My last mobo was relevant for about 7 years, this one maybe 7-9, and one
probably wants
to get something that has a good pci-passthrough layout.
