All the refresh rate on the monitor does is allow for higher frame rates without screen tearing and a more "smooth" and responsive input from devices such as your mouse.
I know this might still seem confusing, so I'll try to sum it up as simply as I possibly can, due to my understanding of what a refresh rate does for game.
I own a 4k 60 hz monitor. This means I can't put my monitor any higher then 60hz. If I play with Vsync "ON" My games will lock at 60 FPS "IF" My hardware can keep it there. No matter what, my FPS will never go above 60, but it can go lower depending on graphics settings and details. What this does though is creates a constant feeling of smoothness, but may cause input lag from my mouse (unless the software has features built in to combat input lag with vsync on). If I turn vsync "OFF", my FPS can go above 60, BUT this means I may be prone to screen tearing, since the monitor is only able to refresh at 60hz or 60 FPS without any screen tearing but gameplay will feel smoother and more responsive above 60 fps.
Now with a 144hz monitor, this means at 144 hz you will be able to leave vsync on if you wish, which will cap your FPS at 144. This don't mean your game will always run at 144 FPS, it just means until you go over that, you shouldn't notice any input lag or screen tearing. In your case, if you are seeing 70-80ish FPS, this is all your hardware is giving you. You shouldn't notice screen tearing or much input lag. Which is normal.
For me personally, this is why I don't even care about the higher refresh rate on the monitor. Most gamers won't even notice a difference in their gameplay experience over 50 fps ANY way. If you lock at 60, it is a much more realistic target to aim for when looking to try to get the most consistent frame rate with no tearing or fluctuations.
Some people prefer to have as much FPS as possible with no vsync on, so this is where the 144hz monitors come in. They can leave v sync off and not notice screen tearing until above 144 fps, and also not get the input lag that vsync usually brings with it. Realistically, with today's hardware, you will hardly run a game at max settings at 144 FPS, or above, consistently, ever. For me, I notice the FPS "drops" and "gains" and it just annoys me.
Just something else to note. Vsync also helps cut down on the heat levels of your video card. If you are playing a game at a locked in 60fps (on a 60hz display), the video card don't need to work as hard since it only needs the performance of 60 fps and lowers heat. With vsync off, your video card will perform at 100% capacity to deliver the highest FPS possible, which also increases heat levels.
Hope this helps.

Also, just like to mention that some games do utilize different forms of vsync when turned on. Sadly, WoW is one of those games. It will cap you where it "THINKS" you should be at. This just sucks since you could be at 40 FPS and then the game will cap you at 30 because vsync will either cap at 30 or 60 or 90 or 120 or w/e and always choose the closest cap based on the FPS you are getting. I think this is adaptive vsync at work, and I hate it.
But yeah. On a 144hz monitor, I'd leave vsync off in all games. Unless you are having heat issues. Then Id just Sync at 60.

Yes and no. Turning V-sync off won't give the OP poster more frames if that is all his hardware will give him. BUT if adaptive vsync is kicking it, it may be capping him at 75 FPS (75hz) because most of the time the OP is playing, his FPS is sitting around 75.
