I need help getting full resolution/acceleration for a Radeon R5 230 on Opencore

I am trying to build a complete system, but I invested on a rather inexpensive card, a Radeon R5 230 (1 GB of Ram). I got all other aspects of the system runing fine, but I am very confused whether this card can be used or if should just buy a more compatible video card. In case you have the tools to help me get this card working on my system, I kindly ask you state your experience on building systems like mine using Opencore, and tell me right away you have the tools/kexts? to get this card working. The work will be done via any desk on the system. I will only consider offers from experienced freelancers who have solved this or a very similar difficulty already. Thank you so much beforehand.
