What about the 5820k? I am also looking for some future proofing. I know I need a powerful GPU but I'm also going to be needing a powerful CPU.
From personal experience, the 5820k is amazing. I'm running it right now, and it runs game perfectly fine in 4k and even 5k.
The 5960x is really for those who want to brag, have tons of money, or have serious business to accomplish. If you have no budget and need it for video editing, go for the 5960x. However, a cheaper variant is the 5820k and the 5830k.
Go with the 5820k, its preforms well, games well, and will get anything you need done accomplished.
