Asus TOP Boost Clock is 1137 outta the box .... stable at 1280 Mhz
Asus gets 3DMark Score of 9340 outta the box and 9839 OC'd
Idle temp is 30C / load temp is 72C
Noise is 37 dBA Idle / 38 dBA under load
That makes the Asus 7% faster outta the box than the EVGA SC, 6C cooler and almost 1/4 as loud under load (every 3 dBA is a doubling of sound level). The FTW is slightly faster than the SC, leaving the Asus model w/ just a 5% performance advantage
