So I bought this card a few days ago from amazon.de and I was super happy with it and all. It has really good performance I have to admit. The only thing that seemed to me as a potential problem was the fact that it was using 70w of power on a simple youtube video on chrome. I don't have that much knowledge about AMD's graphics cards and how much power they draw, but 70w seemed quite a lot.
I am using a single 240hz 1080p monitor.
