Hey GSAPPIT,
I would not recommend any Quadro card at all. They’re specifically designed to work well with CAD applications, RC is not that kind of software. You’d get much better performance for a lot less money when you use an Nvidia GTX/RTX card.
Running Quadro’s in dual is the same deal. Similarly you’ll get about 30-40% better performance (=less processing times) when using a second GTX/RTX card.
