I am going to be using an i5 9600K. I am deciding between the Gigabyte Z370XP SLI and the Gigabyte Z390 Gaming X. I kinda want to use the Z370XP SLI because of its additional USB headers and a better audio chip but I am worried about compatibility. Will the Z370XP SLI ship with a compatible BIOS? Should I risk getting the Z370XP SLI? Thanks!
