First things first, here's my current specs:

ok, I'm upgrading to a solid state drive. I bought a 1TB one from Samsung. (the Samsung 850 EVO 1TB).

I do like Linux (RHEL flavor, so I'll probably use CentOS 7) better as an OS more then Win. I previously had a laptop where I ran CentOS as a host OS and Win7 as a guest; using virtual box.


I'd like to do the same for my desktop (specs shown above). However, I'd also like to get a (or a pair of) really good graphics card, like the nvidia gtx 1080 or 1070.

So my question is two-fold:
1. does nvidia support linux for the gtx 1080, and does anyone currently run that setup (btw, I'm dual monitor).
2. Would the graphics still be good (if I bought the above card) for windows 7 if I'm using that OS as a vm using virtual box?

I don't necessarily do any "heavy" gaming or anything like that on my PC, but sometimes I'll edit a gopro video and I'd like to have the option to game on the windows vm if I end up wanting to. (primary is PS4 console).

not really sure why there's a huge space between my html anchor


UserBenchmarks: Game 13%, Desk 64%, Work 52%


and the start of my html table.

Been out of graphics work too long to say much about the current state of affairs but I generally believe that because of the virtualization layer, performance is still pretty trash. There are a number of people who have done sort of hacked out passthroughs but I don't know the mechanics there but the goal is always to give the VM a more direct path to the GPU. Lately though there have been efforts by NVIDIA and AMD to provide this more officially, though these look more like enterprise type solutions.

So not much help here

This might be a little more helpful, though I don't know how much VirtualBox provides vs VMWare.

Linux graphics all comes down to drivers. My experience would be to go for like a "founders" or base model card, and run it on top of a very common OS. Ubuntu seems to have far and wide the best driver support, most likely because SteamOS is a derivative of it. But "best" can still mean waiting 6+ months for any kind of game optimization; you might see up to 30% fewer frames from any review you read online for blockbuster games.

When I went to an AMD graphics card I gave up and went back to Win10. I feed 12GB of RAM to a Ubuntu VM and it's very hard to tell it's not on bare metal. With the Linux subsystem in win10 I rarely use it anyway. Most open source stuff is cross-compiled or easily runs in the subsystem (FFMPEG, apache, etc.)

However... I too want a 1080Ti; so report back results

virtualized gpu works great, but not with virtual box. You need xen, vmware, or kvm. https://medium.com/@calerogers/gpu-virtualization-with-kvm-qemu-63ca98a6a172

All of AWS/Azure gpus are "virtualized", it just depends on your hypervisor choices as to whether you want passthrough or a vgpu.
