my thoughts, the gigabyte boards are more problematic than most others. cant argue with the pricetag though.
you are going to need an after market cooler. no sense in z68 and a k series cpu and no overclocking.http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
I'm seeing a lot of complaints about DOA in the newegg reviews for that PSU. Quick glance at the newegg sales: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016&cm_sp=DailyDeal-_-17-371-016-_-Product
Hope that helps. I know you have a budget, but in retrospect, an extra 70 dollars or whatever might save you a huge headache.
