ASUS HD 7790 DirectCU II cards offer cool gaming graphics

The ASUS HD 7790 DirectCU II graphics card improves performance through the use of a 1075MHz GPU and proprietary DirectCU II thermal innovation. It runs 20% cooler and significantly quieter than reference HD 7790 designs, allowing for better overclocking. The higher performance ceiling can be tapped by exclusive GPU Tweak, a user-friendly graphics card tuning utility. The HD 7790 DirectCU II offers great value DirectX® 11.1 gaming and multimedia performance with power-efficient 28nm GPU technology. It supports the newest PC games in mid to high settings in 1080p, and can easily handle high definition multimedia content acceleration.

  • OC-selected 1075MHz core, 75MHz higher than reference for smoother gaming
  • DirectCU II achieves 20% lower temps and vastly quieter performance than reference with direct-contact copper heatpipes and dual fans
  • GPU Tweak helps you modify clock speeds, voltages, fan performance and more, all via an intuitive interface.
