Amazing build man, that PSU can support another GTX970 later on, so yea, go for it!
Edit: Actually, you may have to change that RAM. The NH-D14 will not fit with those tall RAM heat spreaders on the way.
For gaming (im assuming this is going to be a gaming build, if not let me know) an i5 4690K and GTX 980 will perform better than an i7 and a 970. I also switched to a better CPU cooler (and this won't interfere with the RAM, which I also changed for a kit with lower timings and price, and got a cheaper but still rock solid PSU. Finaly, do you really need a Blue Ray drive?
