Thnx Guys,that's really helpful.
I have almost decided to go with configuration listed below. I have chosen GTX 680 4GB following by advice from this thread
Adobe Photoshop CS6 GPU Acceleration - Puget Custom Computers Looks like it's the best choice for photoshop. I have also changed case (sad as I really like cosmos II) to cosmos s as it's cheaper and smaller. Cosmos II is just HUGE and without dual processor mother board is no need to go with this.
