The ASUS Maximus VI Extreme board's performance is stellar where it counts, namely in overclocking and gaming benchmarks. Its overclocking performance is helped by ASUS' proprietary DIGI+ PWM systems and the on-board energy-saving EPU chip to allow for precise voltage control. In line with its ROG heritage, the inclusion of a high-speed PLX PEX8747 splitter chip allows gamers to set up a multi-GPU configuration for their extreme gaming requirements. For power users, the OC Panel offers convenience in overclocking and system monitoring. Another bundle of surprise is a mPCIe Combo II expansion card.
