Looking for an IPS 1440p 144hz G-sync monitor



That monitor is FreeSync(AMD) compatible, not G-Sync(Nvidia). And they are not intercompatible. For G-Sync, look at the Asus ROG Swift PG278Q or Asus PG279Q, if you can afford it.
 


Why on earth would you do that? Have you actually experienced adaptive sync technology?
