I own a Asus Gene VII and 2 Asus Strix 970´s in SLI, and lemme tell you that it wasn´t a smart choice. They are STACKED, and the upper card has almost no room for air flow. There´s almost a 12ºC difference between the two cards.... On full load the top one might reach 83ºC and the one at the bottom is near 65ºC. All this is built on a Corsair 350D and im using 5 SP120 fans in the case. If I had known better, iwouldn´t have gone M-ATX for sli, it´s just not that practical, and now I live paranoid due to the temperature differences. And fans on the strix, when above 70% are INSANELY LOUD. So... no , go ATX for SLI
