I've installed two MSI RX580 8G V1 graphic cards in my system which is built using an AMD FX-8350 CPU and has 16GB of memory.
Everything I can see shows that Crossfire is enabled, however, when I run Performance Test from Passmark there is no difference in the results from one RX580 to the two Crossfire connected RX580s on any of the graphic tests. Shouldn't I see some improvement? Am I missing something? Does Passmark correctly measure cards in Crossfire Mode. Performance Test says Crossfire is enabled.
