Not only will this allow AMD to get into a position no other company has, as professional graphics solutions are currently strictly in desktop / notebook form factor.

In other news, we see that Nvidia is preparing for their Geforce GTX 780 card based on the older GK110 architecture which is said to bring only a 25% increase in performance when compared to the Geforce GTX 680. It will be interesting to see how AMD's 8970, which is said to bring a 30-40% increase in performance over the 7970, stacks up against this card from Nvidia.
