Probably the best 34" 144hz 1ms monitor for this price. Was eyeing off the Acer Predator for a while till i came across this one, all the reviews seem to be good. The only thing it lacks over the Acer is the G-Sync but couldn't justify the extra $400 for that.
LG 34UC79G-B 34" UltraWide Specs
2560 x 1080 Resolution.
144Hz Refresh Rate.
AMD FreeSync w/ Cross Hair Feature.
1ms Motion Blur Reduction.
178/178 Viewing Angles.
DisplayPort, HDMI, USB 3.0.
Don't forget cash rewards :)
Good monitor, i got mine for $350, although you have to change the screen into "gaming mode" for 144hz, it looks weird in the beginning, but is good, although the lack of 21:9 content may cause trouble for others
