Right guys, first problem encountered 
Popped in the 290X and fired up and no probs to speak of (2 black screens but nothing to worry about). I install the AMD drivers and the screen flickered badly and black screened after a couple of seconds. Restarted and the same again. I couldn't see anything, so I connected my Asus 1080P monitor as well and so far so good, I change the display to 1080P on the Swift and unplug the 1080P and the Swift flickers badly and a couple of seconds later, black screen.
How do I set the screen refresh rate in the CCC please? I can't see it and even though I have set it to 60Hz for now in the desktop setting, every time I unplug the asus, flicker to a black screen.
Help please.
