I am right now trying to get my HP 390x a custom frame buffer because many people told me that it might be why I need another card for it to work (xfx 7750 makes the 390x work with full graphics acceleration and no issues but has to be the 2nd gpu in the computer) I would like not to have 2...
I have recently put in a 390x into my mackintosh but I seem to be having some issues with the card.
Here is the build:
OSX Sierra 10.12
Gigabyte Z170MX Gaming 5
HP AMD R9 390X Aries-E3 8GB Video Card
Gigabyte AMD HD 7870
The problem I am facing is making the card work...
