34" ultrawide or 29"ultrawide+23" 16:9?

[andrewfh]

im planning to get a new monitor for my room, and I have a choice of 1X 34" ultra wide OR 29" ultra wide with a 23.8" 16:9 monitor. The reason Im choosing against the 34" ultra wide is because two monitors will give a better surround feeling. And I chose a 23" with the 29" ultra wide is because both monitors has the same height, so they won't look stupid.
What combo the best for productivity, LIGHT gaming, and daily uses?
What do you think is the best in the long term?
Im using the late 2014 MacBook pro 13" to power the monitors, will the graphics card be able to handle one big or 2 monitors?
