What are you trying to do, just game?

Also if you plan on upgrading in the future I'd suggest a different PSU. 650 is enough, but I might suggest a 750-850 PSU. Than leaves you plenty of room to add components 

Gaming and for rendering, but mainly for rendering

Okay, I was about to suggest a 4790k but the additional cores of the 5820 will help you a lot. In fact my 4790k only gets beat by 6+core cpu's and with a slight OC I could probably fix that. I'd also suggest looking for builds on PC part picker that use your CPU, cooling solution, GPU and see what their OC temps are, assuming that's something you want to do. It won't give you an exact temperature estimate but it' should be close

Thank you for all your help, its been very useful. ;)

Please let me know if you think of any changes that might help my build.

Those are good parts for rendering, well done! Maybe get a slightly better power supply so u can overclock a lot.

psu a little better as suggested above , also you could add another 2*4 or 2*8 gb ram . SSD , HDD ?

Thanks everyone

If I were you, I'd go all out and make a custom water cooling loop.

Definitely a higher watt Power supply. Look for a corsair gold rated 750 or higher.
