Build quality is super solid and looks much better than the pics - a bit more grown up somehow.
Mine overclocks to 200mhz right out of the box no problems. I'm impressed by the speakers which I didn't think would be the case (although the wife isn't talking too me and I had to turn the sound down about an hour ago lol (I am on the couch tonight btw...although I'm going to play this for a while so no real problems there!). Playing Grid autosport the helicopter sounded like it was flying around me - really liked this surround effect.
The 21:9 with the curve makes for a pretty immersive and great experience...there is some pop to the depth and the picture colour is sharp, rich and vibrant. I've tried a few games - GTAV, Witcher 3, Rise of Rome, Far Cry 4, Just cause 3 and Starwars battle front - all look really good. I've turned up all the settings to max and looks great. My set up is slightly overkill with 2 GTX980ti's and I probably could have gone with the x34 - but I'm thinking although the x34 screen sounds slightly smaller, it could make quite a difference and not be so immersive. Also with everything turned on - dust blowing across the screen etc - I think id rather have this (which adds to the immersiveness) than on the 3440 where i'd still have to turn things down. Pixel density isn't a problem for me with this screen and the high refresh rate is a great benefit. Going for this one over the x34 for gaming feels the right choice. THis is fantastic!
