For the motherboard, I would choose the P8Z68-V PRO/GEN3. The Extreme-Z would be a waste with only one videocard and you might as well choose a gen3 board to be future-proof. The gene-z is popular, but due to the micro-atx size, you would be giving up pci-e slots in exchange for better overclock-ability. For most users, the P8Z68-V PRO/GEN3 is more than enough and you still have the option for more pci/pci-e cards or a second videocard later if necessary.
On the videocard, even though the 7970 is the best (for gaming) at the moment, isn't nvidia more supported by Photoshop and the other Adobe programs you plan to use?
