When Intel's Sandy Bridge platform was launched, P67 Express was perceived as the top of the line discrete graphics chipset that gives performance segment users everything they'll ever need. ASUS hence based its prestigious ROG Maximus branded motherboard based on it, and came up with the Maximus IV series. With Intel releasing a higher-end chipset with the Z68 Express, ASUS decided to redo its socket LGA1155 ROG motherboard lineup, with the Maximus IV Extreme-Z. The new motherboard gives users access to the processors' embedded graphics via a HDMI port, and gives them the benefit of Intel Smart Response technology that P67 lacks.
