Everyone's circumstances are different - I've been busting to upgrade for around 3-4 years now but adult life has got in the way. My CPU does struggle in certain scenarios but when I actually think about it, does it degrade my experience that much in the games I play that it detracts from my enjoyment? Not at all - even though my CPU is a first gen i7 standard Xeon the majority of games I play, barring the Bethesda Fallout stuff and to an extent Forza, are GPU bound at the res I play at. To me, the idea of forking out £400-£500 on a new CPU/RAM and mobo just purely to get a bit more out of my 1080ti doesn't seem that worth it at the moment. However, I do understand the need to up the core count at some stage, and as pointed out in this thread, that day is coming soon enough with the advent of the new consoles, so when that comes around I'll be jumping into bed with Zen 2. If I was sitting on a 7700k now i'd be more than happy tbh.
