Your choice of parts is alright, but most of them are overpriced. Especially that $595 reference blower GTX 980 which should cost less than $550 and the $110 EVGA Supernova G2 power supply, I've seen that model drop to around $85 in the past.
Do you prefer to buy from Newegg only, or will other retailers do? It's possible to make a 5820K-based build for under $1500. The following build includes a better CPU cooler, DDR4 RAM, and EVGA's flagship GTX 980 Classified for a lower price than the reference type GTX 980 you were looking at.

That also includes a case, I'm not sure if you need one or not. I didn't include any storage drives because you haven't listed any, I guess you were thinking of reusing your old drives? You said you wanted a new PC in your initial post, but I'm not sure if that means you're going to be reusing parts from your old PC. Can you list your old PC's specs or mention which parts you're thinking of reusing?
The i7 4790K (or the i5 4690K) isn't a bad idea, you'll save more money with that and you could pocket the difference or spend it elsewhere on things like an SSD or something? I can put together a i7 4790K-based build for you no problem, but tell me what you think of the 5820K build, is that within your budget?
