Ready to pull the trigger?

Hey guys. I made another post not that long ago about some help with my build and I've been happy with it but I'm still having trouble pulling the trigger and finally buying it. This PC would be used mostly just for gaming and I'd love to have it last me quite a long time if possible. I'd be wanting to play games such as GTA V, The Witcher 3, Batman: Arkham Knight, etc. So I'd thought I'd make another post just to see people's thoughts on it and if there is anything I should do or not do with it. I was trying to keep the price under $2500 but it went a little over but not by too much. What do you guys think? Anything I should change or am I good to go and finally seal the deal? Also I heard that this processor gets really hot so I'm wondering if the cooling I currently have in this build is enough or too much? Thanks in advance for your replies and thoughts.

Real nice rig.       Go for it.  

Alright I'll replace the current cooler with the 110i 280 cooler instead. Hopefully I'll be in DS land soon haha

I hope it'll be able to run those games haha. I've never actually been able to run games on the highest graphics and I'd love to be able to do that. Especially with the Witcher 3. The thing that keeps bothering me though is the GTX 970 or the GTX 980. If I were to change to the GTX 980 it would cost too much for me. Hopefully the GTX 970 will do the job. I've never really been good with customizing computers and such.
