Well what is your budget for the entire system?

I would do something like this http://pcpartpicker.com/p/yRvhzy

Take a look at this http://www.anandtech.com/show/8426/the-intel-haswell-e-cpu-review-core-i7-5960x-i7-5930k-i7-5820k-tested/6 Look at the difference between the 5820k and 5930k and that is what you can expect out of overclocking the 5820k.

Don't get a 5930k it's not worth the money. I would do something like this http://pcpartpicker.com/p/MwJRmG I do have to say that I really don't know that much about this motherboard but it looks like a decent board and has nice futures.

Tiny bit over http://pcpartpicker.com/p/2QKGZL

Went a little over budget Intel=http://pcpartpicker.com/p/fYM4Lk AMD=http://pcpartpicker.com/p/QPss3C

I've personally only heard good things about this GPU. The only issue's I heard about the gigabyte versions were for the 390x's but non on the 390's.

I wouldn't use it for any of that however if you really were planing to do any of that then even something like a i5 4460 wouldn't really be the best for that either . If you were planning to buy something like a 980 ti or fury x or mid to high end SLI or Crossfire setup then I would look for a higher end CPU now to make it a lot easier for yourself to upgrade in the future.
