I just knew it was going to happen, I've been talking about a card like this that 's like the 7870 xt with the Tahiti chip, and it has arrived, just guessing< I think it will be priced around the £150 mark..
Not a fan of any of those shroud designs, however, I like seeing AMD add more options. As mentioned above, this is a similar move as bringing the 7870 Tahiti LE out and if the performance/price levels are the same as that card then it should be a very successful addition to the AMD line up.
