Got my SC2 yesterday--it looks amazing! Haven't had a lot of time with it yet.
Looking forward to getting home today and toying with a small overclock for the dark souls expansion.
I did notice that the card is not idling properly, but I kind of expected this. I'm on 1x144hz and 2x60hz panels and was aware of the mixed refresh rate downclocking issue on pascal (worked fine for me on my 780ti). I have a list of things I'm going to try tonight to see if I can correct it, but I'm not too concerned if I can't. The card idles at 1480 core with temps in the mid 50s on the desktop.
