I am very interested by the new AMD Radeon 7850 graphics card because:

- It is silent (tired of having a vacuum noise in my pc)
- It uses less electricity

Well, this is not the most powerful of the market but it will be good enough to run my games on Linux (Thrine and other games of Humble Bundle)

But before buying, I'd like to know if:

- It is easy to install Linux / Ubuntu?
- Stable?
- The dual screen feature works well? (eg display TV + PC)
- What about games under Wine (and other 3D, it works as well as in Nvidia?)
- It is possible to use the audio through the HDMI?

Thank you for your feedback.
