amd liquid vr support?

[jm3]

ok i have a question here tbh its probably because i don't fully understand AMD liquid VR implementation.
i see AMD are claiming that they will be using liquid vr to allow for crossfire support to drive each display in the rift how will this affect fly-inside in the future?
reason i ask is im at a point in my sim project where i will be building a new purpose built computer for the sim to be a standalone system and the choice i have to make is either to switch to nvidia or buy the new fury pro duo from amd. i cannot use cards like my current ones as they are way to long to fit in the custom enclosure on the sim platform (limited space).
