It's hard to prove who or what caused the damage. If you rma the board, gigabyte will inspect it carefully and probably reject it when they notice the bent pins. I would try to straighten them yourself by using a straight edge item, such as a small knife. Place the board under some good lighting on a non conductive surface, such as a box or phonebook. Or just open your blinds, etc. Then carefully move the bent pins slowly to straighten. They don't have to be perfect to mount your processor.
