I'm planning on grabbing a new CPU and motherboard for Christmas (Probably water cooling kit too) So I was going to go for the i7-5820k right off the bat, I even had no problem shelling out more money for the x99 motherboard that I would need with it, however after also noticing I need ddr4 ram the price was looking very steep and that was not even including the water cooling. So lets say I got a 4790k and a z97 motherboard opposed to the 5820k how many years would it last me? Would it last at least 3 years at 4.5 GHz's without being outdated, if not then how would it compare to the i7-5820k at 4.5 GHz's on a x99 motherboard? I am using this set up for mostly gaming however I have been getting into some very light 3D modeling recently so who knows.
