FINALLY my system is working somewhat right:
3D Mark Firestrike - 8771

Now mind you I'm running a 5+ year old system, which is definitely dragging this down.
Now my best score with my 2 R9 280's in Crossfire was 9216 (however in Win 7 I managed a 9646, but since Win 10 somehow it dropped)

I'm a bit disappointed as I figured the RX 480 would beat it, however, its close enough to not really matter at all.
Also, subjectively, the RX 480 ran it better, what do I mean by that? In short, Crossfire sucks. Visibly the RX 480 even at slightly lower FPS had far less screen tearing and ran noticeably smoother and better. The fact it uses 250 watts less at full load helps as well. And finally obviously Crossfire only works on some games, The RX 480 will work on all games.
So in the end I'm still happy with my purchase, I'm glad to be done with Crossfire (for now), and I look forward to any upcoming improvements as the drivers are sorted out more.
