The game is smooth as butter on this R9 280x which surprises me, because most of my experiences with brand new games on AMD drivers have required lots of tweaking or waiting for updated drivers.
Wouldn't going mini-ITX and running a 2nd 760 be impossible?
Congrats on the new board! I think I might pick up a combo at Micro Center this summer. I will be very close to one when I visit relatives in Minnesota in July.
