Do you have any plans of adding a second video card later on?
If your interested you can save yourself some money by going with a smaller psu and a GTX 670. The reason being is the the 670 will get almost the same performance as the 680 but for $100 less.The 670 comes to within 10 to 15 fps of the 680 in a lot of the game benchmarks and that extra 10 to 15 fps is not worth $100 , you want 25 to 30 fps more to pay an extra $100.
