The human eye cannot "see" refresh rates that high, meaning you might not really be missing much. There can be a difficult to define difference in quality between let's say 30 Hz and 60, but not to the extent that it's really obvious. Where 144 Hz and higher monitors come in would be for games like first person shooters where split-second accuracy can be helpful for the player to succeed. But sims games don't work that way, time management in the game is much more relaxed than that. As I like to keep saying, your sim was going to burn those waffles and be late for work anyway.
The reason I asked if you had an iMac is that I am pretty sure none of them have monitors above 60 Hz and it's not like we can swap them out even if we wanted to. Even the super fancy iMac Pro beginning at $5,000 (USD) has a 60 Hz monitor (actually made by LG), I don't believe there is any such thing as a 5k monitor that can run at higher refresh rates.
