A 5-10 year old machine can still be perfectly usable. I have a 2012 laptop with a high end i7 3-series CPU, high end Quadro GPU and I would hate if any of them failed because it's not something I can easily (if at all) fix, the whole laptop would become a doorstop.
An i7 6700 is already 5 years old. That's most certainly not an outdated "can throw away" CPU. Neither will a 3rd gen. Ryzen 4 years from now.
