Hello. What do you think is the better choice for GA flying…? The RTX 3070 or RX 6700 XT with a RYZEN 5 5600X CPU? Thanks! 
MSFS tends to favor performance with Nvidia cards compared to AMD. However, the difference isn’t very huge and getting an RX 6700 XT would do just as fine. If pricing isn’t a problem, I’d go with the RTX 3070.
