Today we look at the new customised high end card from Asus, the GTX780 Ti Direct CUII OC. This solution features a customised two fan cooler and out of the box overclocked speeds. We already know the GTX780 Ti is the fastest single GPU on the planet, so how does the tweaked ASUS card stack up?
The ASUS GTX780 Ti DirectCU II OC is equipped with the DIGI+ VRM circuitry which gives the card a 10 phase power design. Asus claim this reduces the card's power noise by 30 percent and makes it 15 percent more efficient.

The new ASUS GTX 780 Ti DirectCU II OC is clocked higher than the reference GTX780 Ti. The GK 110 core speed has been increased from 876mhz to 954mhz.
Today we test hardware with a 30 inch Apple Cinema HD display (2,560×1,600) and with our ASUS PQ321QE Ultra HD 4K Monitor (3,840×2,160).
The 4K ASUS PQ321QE panel retails with a whopping £2999.99 asking price , however we would expect this cost to drop in 2014.
Setting up this monitor is simple with both AMD and Nvidia hardware (via DisplayPort cable) and we didn’t experience any issues. To achieve a refresh rate of 60hz after the Forceware or Catalyst drivers were installed we enable the Multi Stream Transport mode within a submenu of the Asus PQ321QE.
Today we test using the latest Catalyst and Forceware drivers (13.11 beta and 331.82 respectively).
