Let's be real he isn't going to notice the difference, he's using 32gb of ddr4 so he is on a modern cpu and has a 1080ti so it can be assumed he is running at least a 6th gen i5, maybe he would see a 1-2fps increase, maybe. I have a similar system, 7700k, 1080ti but only 16gb of 3200mhz ram. changing the ram speed down to 2400mhz or running xmp or even overclocking, gaming results are within margin of error, 1% and 0.1% lows included.
