Upgrading ram does nothing these days. It's just the 'thing you put in your motherboard'. You put in whatever it needs. Technically, if anything, it's been getting slower.
Normal DDR3 usually comes in 1600 and 1866 usually, and range from timings/cas of 8-11 and 10-13 respectively... DDR4 @ 2133 goes from 14-16. Doing the 'maths'..
The slowest DDR3 clocks in at 7.0ms, and the fastest at 5.0ms. The slowest DDR4 clocks in at 7.5ms, and the fastest at 6.6, barely faster than the slowest DDR3.
Really, the only benefits to DDR4 is A) It has some features that nobody really sees or cares about, B) It's compatible with your new system. Speed wise it makes absolutely no difference in 98% of applications.
As far as the GPU goes, depending on who does more GPU gaming, you might want to consider giving the 970 to your girl, and picking up the new card for yourself, be it a 1060 or 480
