It's quite a beast, ASUS markets it as the fastest GeForce GTX 980 card in the world with a 1317MHz core clockspeed and 1431MHz Boost! It has 4GB GDDR5 memory clocked at the usual 7010MHz and is cooled by the ASUS DirectCU II with 0dB fan technology.
Special features include DIGI+ VRM and 14-phase Super Alloy Power, Japanese 10K black-metallic capacitors, memory defroster, and a one-press VIOS reload safe mode. The 20th Anniversary logo on the card is a color-coded load indicator, it changes from blue to red depending on the GPU load.
