Comment on Looking to build my first PC in almost 30 years; What should I be on the look out for?
catloaf@lemm.ee 4 months agoYou put one GPU in one PCIe slot and one in another. Just be aware that just because a PCIe slot is full-length, it doesn’t mean it’s a full-speed x16 slot. Check the manual to be sure. Most cards will work with fewer lanes, but not all. And of course it’ll be slower. (Fun fact, you can put a long card in a short slot. Some have open backs to allow this, but if you have an oscillating Dremel tool and a steady hand, you can make your own.
But personally, for basic 3D games and work, I’d just use the integrated video (which is on the CPU these days, not the motherboard) and give the discrete card to the VM.

With the conversations I’m having here, I’m leaning in the direction of integrated video (assuming I can get one with display port) and a discrete card just for AI work.
I use VirtualBox for VMs. I’m assuming there are instructions on how to give the card to the VM? My cursory google search came up with dubious results.

Looks like PCI passthrough was dropped in virtualbox 6.1.0. You may want to use Qemu or KVM.

That.

Most new boards will have at least a display port and an HDMI port. Add that most also have Thunderbolt4, plug in an HDMI or Display Port dongle. The sky is the limit man. On the VM panorama, VMWare is now all fucked with their forced subscription model, Virrualbox is still a thing, but GPU passthrough (I’ve heard, can’t really confirm) seems to have turned into a real shitshow. KVM / Qemu seems to be the only alternative that makes sense right now.
