Thanks for the help!!
I have decided not to use these gpus xfx, I will finally try to buy sapphire, msi or gigabyte that are gpus that I know.
Probably what I would save by buying xfx would later lose it with heat problems
Nvidia cards is the best option if you want to mine other altcoins compared to AMD cards that only few coins that you can mine.
Try RTX series RTX 2060 or check the gtx1660 ti which is one of the best options nowadays. Base on profit.
