I wanted to get them and was ready to buy but for some reason a while back i changed my mind the monitors are quite expensive

playing with 2 monitors is not that much of fun i think ;/ confuses you :P never tried it.. i have a second screen but thats just for monitoring stuff and chating while i watch movies + it looks cool :D

120 MHz gives you 120 FPS which feels more smooth/faster for some not everyone can see it

1440P give you 1,6 million pixels more then 1080P or 80% more which makes games look so much better

you have in 1440p these 2 choices the best of the best
