I'm not going to give advice. Because if it doesn't work for you, I don't want to be liable. I know one of the guys I fly with says just running 1 RTX2080 is significantly better. So, if SLI'd; I couldn't imagine the settings you'd be able to run it at. For me, it was all trial and error until I got the settings and quality where I felt really good about it. When I have more time, I'll pull up the resolutions the pimax is running at.
