EVGA 780 Classified is the best 780 you can get. It might run a few degrees warmer than the Asus, but that is because it is already overclocked more than the Asus. Base clock for the Asus is 889MHz, while the EVGA classified is 993MHz. For the extra couple bucks, the EVGA is a much better buy.
simple... with the software provided by asus, ramp up the speed to 993 MHz, and BINGO! same speed... however i do like the look of the asus cards more, and im pretty sure it'll still cool better then the EVGA card due to the fans unique design (in the youtube link below) so i say good choice for choosing the Asus card
