This thing is absolutely amazing to use as a day to day pc for word documents and excel sheets. The amount of stuff that can be put onto a 1440p screen is stunning. Coming from an Xbox 360, gaming at 1440p on it is gorgeous to say the least. I scored 47 FPS on ultra everything with 8x AA on 1440p using Unigine Valley. Playing BF4, Metro 2033, Metro Last Light, and others I've been using pretty much maxed out graphics settings and haven't seen a bit of lag yet. Very happy with my build.
