If u can afford it, get 2600K, as it is great for the video and photo and audio editing.
But if u don't do any of these, it will be a waste of money and all the gamers here will tell u to get a better GPU : )
I edit videos as well but gaming is my main priority. I can deal with a little bit slower video editing for $100 less.
