The 5600XT is a much faster card than the 580. https://www.anandtech.com/bench/product/2524?vs=2580 PCIe 3.0 will not make any difference in performance of the cards. Also look at the RX5700 as that isn't much more expensive than the 5600, it has more RAM, and is overall faster. https://www.anandtech.com/bench/product/2523?vs=2580I'm looking at both of this and can't decide on which one to buy, the 5600 is going to be in PCI-E 3.0 so I don't know if the difference will be justified. Also I'll be playing X-Plane 11 or MS 2020.
