I am not with Laminar Research or Laminar Research; just a flight simmer from down under.
Considering your login name, you have an association with an aircraft with the same registration and most likely living in the USA.
Have a look at the videos in the following link found at https://www.youtube.com/user/col2mab/videos produced by Michael Brown. Michael owns and operates a PC supplier company called XForcePC and Laminar Research recommends this company to supply PCs capable of running X-Plane.
In particular have a look at a video created about 3 weeks ago whereby Michael performs comparison tests with the RX580 card.
I understand this is an AMD card. AMD GPUs and CPUs haven't performed as well as NVidia GPUs and Intel CPUs.
Unless changes are made in the planned 11.30 release, X-Plane does not work in SLI mode.
How many monitors. Consider the advice in the videos from Michael. If you live in the USA contact Michael for confirmation.
