Solved! Help build PC for Multi-user VR Gaming via Virtualization

[remnantdirector]

Hey Friends,

I am in the US and I'd like to build a multi-user VR PC that allows me to run four players in VR by using Virtualization and passthrough to put each player on a separate graphics card all in one machine.

I am using (4)four SteamVR based headsets and running them all using the same SteamVR base stations. Each player also needs HDMI and more USB 3.0 connections.

I'm considering using RTX graphics cards if possible and planning to have 32 gigs of RAM per player. A lot, I know.
And I am trying to put this all in a rack mount.

I'm trying to keep my budget under $8k max.
I don't really know what to purchase or what exactly is available.

Thanks in advance for your thoughts and help!

You are going to want lots of PCIe lanes. I would recommend a threadripper CPU and motherboard to provide the graphics card connectivity.

Oh, good to note. Are the motherboards branded as threadripper to? That's all AMD?

The AMD X399 motherboards are the correct ones for TR4 socket -- https/www.amd.com/en/products/str4-platform . The Threadripper has 64 PCIe lanes. That will give your 4 graphics cards full bandwidth.

I don't do VR so I don't have a graphics card minimum to recommend. But you probably want to think about a custom water cooling to handle the heat.
