Oh thank you, this is very helpful. What a great way to ruin the other 2 points that were actually informative. Was it needed at all? My question is legit, I'm not massively familiar with Intel CPUs, always have been using AMD (and I'm not even familiar with current AMD CPUs these days).
He probably just means that trying to build a rig that'll be good for a few years/a generation is pretty much folly. We just don't know what games will look like in five years ya know? Might be fine, might not be. Anyway, you listed a non-K series proc initially and a K when you asked again. K is for over clocking (and require a suitable motherboard) which will go a long way towards the elusive "future-proofing."
that's a dirty word 'round these parts 

Edit: for gaming 16GB RAM is more than enough. Really not necessary but not a bad investment if you do image work or hella multitasking I guess. 8GB is standard.
