hey guys, i am looking to upgrade my GTX 660 to one of the two graphics cards listed in the title of the post. there is only a $10 difference in price and im wanting to know which is better for gaming. im assuming the 770 will be better, but i just wanted to understand why they are so close in price when the rest of the 760's and 770's i have seen are seperated by $100 or more. i hope that statement made sense....
