Introduction
AMD recently released their Radeon HD 6790 Series which is a trimmed down version of the HD 68xx, based on the same GPU chip but with reduced performance. Priced at $150, right in the gamer's sweet spot range, the card offers plenty of power for gaming at up to 1680x1050.
HIS has equipped their IceQ X Turbo version with the company's new IceQ X heatsink which uses semi-transparent blue plastic cooler. The clock speeds of the card have also received a healthy bump, up to 900 MHz core and 1100 MHz memory.

The Card
Following the color scheme of the other IceQ X cards, HIS is using a blue PCB with a transparent blue heatsink and matching fan.
The card requires two slots in your system.
Display connectivity is two DVI ports (one single-link, one dual-link), one full size HDMI port and two mini-DisplayPort outputs. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Board partners are free to combine several TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time.
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 interface is DisplayPort 1.2 compliant which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.
You may combine up to two HD 6790 cards from any vendor in a multi-GPU CrossFire configuration.
