I'm rocking an i5-3450. Should I upgrade? Probably not. Do I want to? Yes!
I have the money to play around with at the moment and I'd like to build an entirely new system, new case, everything. I don't particularly think anything's wrong with that.
As someone else has said - If you sell your Z97 after going to x99, then sell your x99 when going to Z170, you probably won't be losing that much money, and that satisfies the hobby of an enthusiast. They get to spend time doing what they enjoy - playing with shiny new components, there are much worse hobbies to pursue.
