just purely for the question no, wont get the benefit of 144Hz displaying 80frames. All though looking at it the other way 80Hz/80Fps is better than 60Hz/60Fps.
Get yourself a 144Hz Gsync monitor, its variable refresh rate, you'll make use of 80FPS that way and as a bonus can go up to 144Hz if you play a game or upgrade GPU in future that can do so.
