Hmm trying to do "budget" triple screen is like trying to do "budget" Ferrari's / Lamborghini's. It's possible to acquire a high performance car and strip out all the accessories / features but it kinda defeats the purpose. If your going to spend the money building a three monitor setup for "gaming", then you might as well go all the way and do it properly rather then stopping halfway with a mediocre experience.
Theres always a sweetspot.
Let's say you had a company with 5 employees that did some analytics.
Would you get each employee a decent PC
OR
Buy a supercomputer for a couple million.
Theres a limit in terms of cost/benefit/need.
But I do agree on your overall ideology. If you are into gaming, immersiveness, triplescreens or whatever, go all the way.
Example:
You could buy a cheaper GPU and play games on med/high settings now and 2 years later buy a new card
OR
Buy a really good GPU and run every game in Ultra for at least 3 years and then efter 5 years (still running games at med/high) get a new card.
Which would be a better experience? Which would be cheaper, in the long run? Usually highend GPU.
But that doesn't mean 4 x Titans.
I'm comparing a 150-200$ GPU to a 300-450$ GPU.
Sometimes it pays to not be cheap =).
