The ASUS HD6870 DirectCU brings a very refined aspect to video cards. In addition to the Radeon HD 6870 GPU overclocked to 915MHz, the ASUS HD6870 DirectCU brings a slew of ASUS exclusive features and technologies. Naturally, the card is fitted with ASUS' DirectCU cooling system, complete with three direct contact copper heat pipes and aluminum fin array, dust repellant shroud and variable speed fan. Under the shroud, you will find ASUS' exclusive Super Alloy design featuring the highest quality capacitors, MOSFETs and chokes for improved performance, lower heat and longer life. It also needs to be noted that the stronger nature of Super Alloy technology certainly helps in overclocking, especially with the HD6870 DirectCU's unlocked voltage in the BIOS. To aid in overclocking ASUS includes their Smart Doctor software to assist you in easily and safely overclocking your GPU.
