It will be a rather considerable jump:
As your moving to 5.0GHz or higher across all cores, so a solid 500MHz gain.
Your also gaining two additional real cores and also hyperthreading so 3x times the amount of threads which anything that has multi-core support will see a dramatic performance boost.
Also 3000MHz on memory boosted to around 3600-4000MHz due to the OC mileage.
In short the raw processing power of your rig will be as good as it can really get without going too extreme and looking at i9 where the CPU alone can cost more than that entire bundle and not really offer any gaming benefit.
The Intel 760P is also a whole lot faster than an 850 EVO, talking more than double the performance.
So yes its a good upgrade and more than powerful enough for any new graphics card which may come and a 4k high-refresh rate screen.
