So I assume that it was a decent (not so costly) upgrade.
Would you say that overall you have achived 10%~15% performance uplift as advertised.
I read quite a few reviews that showed a very good ~20% increase in performance from stock 1700X to 2700X. At 4K gaming I have a Freesync monitor with minimum range of 33Hz, the 2700X does help keep the minimums above that range. VR runs at a lower resolution than 4K and a CPU bottleneck is will be much more noticeable and the 2700X is definitely and improvement there.
