My vote goes to the EVGA GTX 770 w/ ACX Cooler.
Agreed. EVGA makes amazing GPUs and the ACX cooling that they offer on many models really helps keep the card running cool. I have an EVGA GTX 780 Ti superclock w/ACX cooling and it does not go past 45 Celsius. Of course I have a large case and a handful of fans so that helps, but even while playing intensive games the temperature remains very cool.
