I'm really looking to get the $700 27 inch asus monitor. Right now I have a 660 Ti, I don't think that will suffice for 1440p gaming. I'm looking to play Witcher 2, BF3 etc. at at least medium settings at that resolution. I was eying a 7970 but just want to post here before I pull the trigger.
Have not heard anything about that particular monitor/brand... anyways to me it's worth the extra $80 to buy a US-branded panel that has HDCP support and multiple inputs (I know the Catleap's don't have HDCP and so I'm guessing that Irun also doesn't have HDCP).
I've heard mixed reviews about those monitors. Some are delighted and some not. The price is incredible and it may be worth taking the chance. There are various models and deals from those Korean manufacturers with pixel guarantees and replacement guarantees. Some only support dual link DVI but lately I've seen some with other connections. I'm seriously thinking about one because I can't afford an HP or Asus.
