It has certainly been an interesting couple of months for the high end gaming enthusiast. In October AMD brought out their R9 290 and R9 290X which took the performance crown from Nvidia. We felt both cards were fantastic, but the substandard reference cooler forced us to offer a hesitant recommendation, and we have advised people to wait on the custom cooled solutions. The Nvidia GTX780Ti was then released earlier this month, reclaiming the crown. While AMD partners still scramble to bring improved R9 290/290X models to market, Nvidia are already a leap ahead. Today we review a highly customised, overclocked three fan card from market leader, Palit.
Palit claim the Jetstream cooler will be 7dBa quieter than the reference design while dropping temperatures by up to 10c under load.
Three fans cover the full width of the PCB, two of which are 90mm in diameter, and the other 80mm. These are optimised to deliver substantial airflow across the heatsinks underneath. The board has adopted an 8 phase power delivery system to enhance overclocking and stability.

The new Palit GTX 780 Ti Jetstream is clocked much higher than the reference GTX780 Ti. The GK 110 core speed has been increased from 876mhz to 980mhz.
Today we test hardware with a 30 inch Apple Cinema HD display (2,560×1,600) and with our new ASUS PQ321QE Ultra HD 4K Monitor (3,840×2,160). It will be interesting to see if the GTX 780 Ti’s 3GB of GDDR5 memory will be a limiting factor powering the latest games at 4K.
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 beta9 and 331.82 respectively).
