From what I understand, the performance increase wrt to the i7-4790K in current games is small but my aim is to build a future-proof PC with a life span of at least 4-5 years so I don't mind the extra cost if future games may benefit from the newer CPU model.There isn't much of a difference performance-wise. I'd say it depends what's available in your area and the price. Go with the 6700K if you want DDR4, but there isn't a huge difference in performance there either.
I have a colleague who is very knowledgeable in PC H/W perfomances and I already told him that I would make "use of his services" …but he is on Holidays now so I just ask here for some pre-advice.
