If you are using the monitor for gaming and you have SLI or Crossfire in your rig or your card can push more than 60FPS to your monitor I would suggest getting a 120HZ or 144HZ monitor. I am in the process of getting the ASUS VG248QE. I get screen tearing because I have 2xGTX 660's OC edition and almost all games I play get 60+ FPS. I deff dont want to have to use VSYNC, its shotty and causes more headaches then seeing those screen tears.
Trust me, I have already scoured the internet reading about this. Save another 100$ and get a ASUS or BenQ 144hz monitor, from what I've red you wont regret the decision. I bought a 27 inch BenQ and its 60HZ with a 4MS response time, its a great monitor but not for gaming, so now I have to spend another 300$ and get a 144hz monitor, but its worth it IMO.
