Monitor Stand For Dell 27 Ultra Sharp

Hi. I recently just bought a third Dell 27 Ultrasharp U2715, but I am planning on returning it, since it is crucial for me to have a monitor stand for this. I am currently following along this guide for Dual Monitor Stands and Triple Monitor Stands but I have a hard time finding a triple monitor stand. I really want the best of the best, looking for something sturdy. Since these were not cheap monitors and I don't want to take any risks for these beauties. 

Also I am up to this dilemma whether I should return the 3.th monitor or not? What are the benefits of having 3. monitors, I really just bought it for gaming purposes, but is there any other reasons to buy 3 monitors?
