Most people with 100+ Hz monitors aim for 100+ fps, which mean games will become CPU bound in most cases, even at 1440p, or higher.
I have a 1440p 144 Hz display and a CPU with almost exactly same single threaded performance as Ryzen has at approx 4 GHz. For reference, that CPU is firstname.lastname@example.org GHz.
In my opinion not as many people with 144 Hz displays will care about hitting full 144 Hz over, say ~100 ... 120'ish fps as one would assume at first glance. The reason for that is variable-sync tech. Thing is if one is going for 1440p or up and high refresh display it seems nowadays to have commonly either freesync or g-sync. A feature which I considered at the time of buying the display as just as additional nice to have gimmick. It actually makes quite a surprising amount of difference I would say. If the display has some form adaptive sync and there is a matching brand gpu present then it really will not matter much if you are not sitting always at flat 144 fps with v-sync on but sometimes can drop couple dozen fps under it.
I am CPU bound btw. Running Planetside 2 with custom useroptions.ini for getting rid of shadows and blinding particles and other stuff that are more of an distraction and in the process culling as much CPU overhead as I can. I can hit at approx 140 fps looking at one specific corner of the warp-gate, normally hovering somewhere between 100 and 120 in medium fights and if the fights hits 96+ vs 96+ level my fps goes to dumpster like everyone else as well. As far as down as mid 40'ish if I get more than few dozen actors into my field of view simultaneously all doing something. Most MMO's can be pretty brutal on CPU's.
I think the Ryzen CPU's are pretty solid options although I also think 7700k and its i5 sibling still has its specific niche. I am sitting atm on the fence in regards of if I am going to switch to ryzen this summer or will drag another year out of my CPU to see what X299 and the AMD "enthusiast" platform supposed to come in the autumn put on the table.
