This was my own findings when I upgraded as both Gears and Destiny 2 had really noticeable frame drops and minimums that were too low for my liking.
Ryzen 1600 @ 3.9Ghz.
Intel 8700K @ 4.8 Ghz.
Granted this is a benchmark but in online games I would see drops to 90 fps on the Ryzen while on the Intel it's locked to 144 fps and never drops even 1 frame. Unlocked it averages over 180 fps on ultra with max frames going over 200. My monitor is 165 Hz so that's why I keep it at 144.
During public events I saw drops to 50 fps in Destiny 2 on the Ryzen while on the 8700k the minimum was 90 fps.
I agree that the Ryzen cpus are great in gpu limited situations but if you need higher than 100 fps consistently then I would go with Intel or wait until Ryzen refresh which is soon.
Those benchmarks in the above post are with a Vega gpu which may be more limiting. 1080ti is faster and consider the next generation will be faster as well.
