I have not own any of these monitors but I need to know what monitor is right for me. I mostly play FPS games, currently BF3 and I have eyefinity 3x20in displays with a resolution of 5076x900. I noticed eyefinity wasn't at all that good for my gaming, it made me feel a bit nauseous. Don't get me wrong, I love it but it only happens when I play FPS games for some reason. Racing games, Flight simulations or Third person view games probably is best for eyefinity, IMO. And I've heard lots of people goes with bigger screen and higher resolution. The Hanns 28in monitor is 27.5" with 1920x1200 resolution while the ASUS 27" has a resolution of 1920x1080.
