I assume swapping my GTX 760 with a latest generation card would give me better gaming performance.

Most games will get a huge bump just with a new GPU - You'd do well with an RTX 2070, or the next generation AMD GPUs (speculating - but there's a lot of momentum on that front).
That being said - LinusTechTips did a head to head benchmark comparison between the i7-7700k (the latest my Z170 chipset can handle) and this 3300X. Bottom line - the 3300X is an insanely good value for performance.
Whether it'll make an immediate difference to you is game-dependent, but if you play a lot of AAA titles I'd definitely look to upgrade soon.
That said, there are cpu heavy games out there, like MMOs with high on screen player counts, simulations like Cities Skylines or flight sims, so your mileage may vary.
