"ASUS thought of the overclocker when manufacturing this card. Proof of this can be seen by the cards "Probelt." The Probelt will allow the user to check GPU, Memory, and PCI-E voltage at anytime with a multimeter. The card is also equipped with ASUS's "Super Hybrid Engine." The SHE should give us 54% better OC stability, as well as scoring 19% better then the average 5870. Not only that but ASUS included an "Extreme Cooler", which should give us a 13% cooler card. ASUS even included a "Real-time Hardware Loading Monitor" built right into the card."
