which RTX 2070 model is most suitable for a Quad GPU setup

[demoan666]

Hi

I am trying to build a quad GPU setup primarily for assisting in houdini simulations (some of their solvers has OpenCL options) and redshift and octane renderings.
which RTX 2070 (as they have the best bang for the buck) Model would be most suitable in a fractal design R6 Case for a quad GPU setup on a ASrock taichi x399 with a 2950X TR and 32 GB of RAM (if you have better suggestion for the motherboard please do let me know).
i would appreciate a lot if some of the testers and experts could shed some light on this

thanks

If you're not watercooling this is probably the best type of card when stacking VGA's: https://www.asus.com/Graphics-Cards/TURBO-RTX2070-8G/

R6 case has 7 slots so it might be an issue as that is a 2 slot card.

Looks like enough spacing between PCIe slots on the Taichi.
