Your machine has Wintel type hardware, normally able to run Windows via Boot Camp, if the minimum requirements are satisfactory. I haven't looked up that GPU before now, so let's see what I find, shall we?

If there were, indeed, drivers to use, the GPU trails behind the minimum. I see what you mean about drivers, though. There is no matching Windows device in this case. You'll have to sort that situation out with AMD.
P. S. There was a second, generic post with a nonsense subject line, that I left where you had posted this one, the wrong forum )Dragon Age). Was that a duplicate or what?
