Isn't this old news? They were announced quite a while ago. The reason they don't have output codec is because they are specifically built for mining. They're still 2-lane slot, and actually, initial test results show that they aren't stacking up to the claimed hashrates.

There's also an unboxing/test video of the MSI and Galaxy ones here:

The sapphire mining cards are also available for preorder on overclockers uk.

So yeah, not really new news. Sorry. :(
