Laptop using GPU of a Desktop?

[Allesmoeglichee]

Hey all,

 

so my roommate and I have been wondering if this sort of setup is possible: I want to build a computer with two GPUs in it. I would use 1 GPU for myself and "offer" the other GPU for my roommate who can access that GPU with his Laptop. Is this possible? (Planning on buying 2 1080tis or, if possible, a 1080ti and a RTX 2060)

 

added the layout pic to visualize our setup a bit better, hope that helps

 

Thanks all for your input!!!

Why not just use Steam streaming so he can play games from your computer on his laptop? Seems easier than running cable.

I never used it but from what I understand, he would then use my CPU and GPU to run the game on his laptop. If I want to run my own games at the same time, then I think we would run into performance issues. Thats why I thought a dedicated GPU for me and 1 for him, while we both have our own CPU would be best.

Not the way you want it.

as long as the end result is the same, im okay with doing things differently. is there a name for this sort of setup? then I can look for some online guides

you mean as a virtual machine?

you can do this with unraid, split the resources in 2, one system can be used by you.

And the other with a remote desktop from your friends laptop.

Dedicate each gpu for each OS.

At that point I'd suggest just getting an external gpu enclosure, seems like I'd be simpler to set up.

It's like not even worth trying. Get an encloser for an eGPU and done

With a pair of 1080 Tis cranking, it's worth a shot imo. Worst case scenario, you have performance issues and can say you tries.

What laptop? Does he have thunderbold? 

Else an external gpu is gonna get tricky (pcie m.2 mods exist but I would not recommend that if you want an elegant solution) 

 

Gaming over the classic remote desktop won't work properly. I only see a vm plus steam streaming as a ok gaming experience. 

 

But to be honest, depending on his current laptop maybe a ryzen 5 2400g or 2600/1600 + 580 plus monitor and peripherals would maybe be cheaper than a 1080ti plus enclosure and a better gaming experience
