Looking to build my first pc for gaming. Can someone tell me If my parts are compatible?

Solution
it's a good build
however no reason to go for 980Ti when the the 1070 provides the same or better performance for less money
upgraded the cooler as well. you can go of course a bit over the tops and get a Noctua NH-D14 ($70) as a cpu cooler but it's not necessary
