Don't think the Fury X supports HBCC, think that's Vega cards. I did update the BIOS to the UEFI one. Most game ran really well, RDR2, Borderlands 3 and lots of others, its still a very usable card, just felt like upgrading. Diablo 3 runs much better on the Fury X than a 5700XT, probably a driver thing as its an old game.Activate HBCC if still an option on the drivers, as it was few years ago.
FuryX supports memory compression, you shouldn't have issues tbh except on really horribly optimized games.
Also make sure it has the UEFI bios not the original one. It would improve performance and overclocking.
