ASUS is using their DirectCU cooler on the HD 7770. We have seen this termal solution before, on many cards from the company, for both ATI and NVIDIA.
The card requires two slots in your system.
Display connectivity options include one DVI port, one full size HDMI port and two mini-DisplayPorts. You may use all the outputs at the same time, thanks to AMD's superior display output architecture.
An HDMI sound device is included in the GPU, too. It is HDMI 1.4a compatible which includes HD audio and support for Blu-ray 3D movies. The DisplayPort outputs are version 1.2 which enables the use of hubs and Multi-Stream transport.
You may combine up to two HD 7770 cards from any vendor in a multi-GPU CrossFire configuration for higher framerates or better image quality settings.
