Does it support multiple graphic cards?

Can I mount two GeForce 2080 cards on my PC and double the resolution?

Would be a waiste of money.
Most vr games does not support multiple graphic cards

What you are referring to is called SLI (for NVidia). It is a feature which requires built in support from app/game developers (which is rare) and the performance gain is inconsistent between apps. You could get +20% performance, you could (rarely) get +90% performance, but you would generally expect to get +50% or less.

At those sorts of performance gains it is better to just get a better single graphics card since it would be cheaper, faster in most situations, use less power, be less complicated, etc.

The main use case of multi-GPU is for workstations (where you can fully use each GPU) or for adding a GPU onto a last-gen system after that generation of GPUs have dropped in price.

Vr games wont give you any boost whatsoever.

Such a shame for VR, as GPU is one of the most important bottleneck for its future.

Our only hope is eyetracking, with foveated rendering.

The only thing you can use a ā€˜secondā€™ card for is PhysX Processing, but it is not worth itā€¦ I have tested with a 2080ti as my main card and a 1080ti as Physx but the results are not worth itā€¦

SLI is just a tech for you to spend more money.

I would recommend never to do it, always sell the previous gfx card, and buy the most price performance version

SLI does work in some specific instances, just not VRā€¦ YETā€¦ VR Is a great use case for one vid card per eyeā€¦

Unfortunately, no one builds the graphics card that is powerful enough to drive the 5K+/8K/8KX using ā€œultraā€ graphics settings at Large FOV. If someone did, most of us probably couldnā€™t afford it. The card I want probably wonā€™t exist for at least 3-5 years.

Yeah probably be a while until not only the GPU but also the CPU hardware catches up a bitā€¦ Better programming is our best bet at this pointā€¦

Yes, it is. If developers would make use of the available driver features for VR (like multi-projection) that would definitely help.

There are so many places better programming can helpā€¦ from games to compositors to ā€˜homeā€™ environments. Programatically, just about every aspect in VR can be improved. If we spent more time chasing these modifications, every headset would be improved.
