We do some performance testing with the ASUS GTX 670 DirectCU II from one card all the way up to 3-Way SLI.
The ASUS GTX 670 DirectCU II the coolest and quietest 28nm card. The TOP version of the card is overclocked to 1137MHz core, that is 157MHz higher than reference. The card also features DirectCU II that uses flattened copper heatpipes to make direct contact with the GPU surface so heat is dissipated efficiently, delivering a 20% cooler and vastly quieter performance than reference. DIGI+ VRM with 8-phase Super Alloy Power technology delivers precise digital power and enhanced durability for stable overclocking. GPU Tweak utility helps you modify and tune clocks (including new boost clock settings), power consumption targets, voltages, and fan performance via an intuitive interface.
