Should I buy 2 LG 34UC79G-B(Or similar models) or 1 Alienware AW3418DW(Or similar models)?

Depends on what you need the extra space for.
For example in gaming, it's really annoying having the bezel of both monitors going right down the center of the game but in photo editing where you can have the image on one screen and all your tools on the other it works quite well.
