i7 7700k memory

[SethK]

I have a 7700k on a Strix Z270H and I'm running 2 x 8Gb @ 2133. (stock speed)  + RX 480 if that matters

 

I found an amazing deal on some trident Z neo 2x 16 @ 3800 but dont know if I can even use it with my processor. The MOBO supports all speeds up to 3866 so I should be good to get that fast stuff right? if not, a slight downclock?

 

How much of an improvement should i expect? for reference I run ~80 FPS on GTA V 1440p high settings i believe. It could be high but i probs lowered the FPS killers. Dirt 5 is meh FPS wise but i think I blame my gpu for that.  cities skylines runs smoothish. Its not a bad system but has its moments of weakness

 

I just want to know if the speed increase is a boost that's worth the price, because I could save half by buying an identical kit of 2x8 @2133. So will my i7 7700k be fine running that high 3800 memory well? if not, im stuck with buying a lame identical kit.

Depends on what exact kit and how well your IMC does. 

Any decent B-die kit you find 3600mhz with 16-16-16-36 timings will certainly OC to 4ghz.
