I have 2 systems, 1 with 3 Gsync ROG Swifts 144hz running at 7830x1440 resolution, and also a system running LG Curved 34" IPS 3440x1440.  Personally i love the Surround monitor setup. That is my main gaming Rig, if you have the desk space and the horsepower its a more immersive experience! The 21:9 monitor is also fantastic, however i wish it had a higher refresh rate than 60hz. I won't go back to gaming on a single 16:9 Monitor

I have had both. I went from surround @ 60Hz to 21:9 @ 60Hz and then back to surround @ 120Hz.
 
Personally I think a 42" 120Hz 3840x2160 would be the next set I will try once they are available (If ever).
 
Everyone has a different experience or preference. I for one have found the surround to be far more enjoyable and frankly a gaming advantage because I see more real estate in games than any single monitor can provide. And I need that advantage in order to have any chance against the better than average players. It fits my "eyes" in more of a natural way.
 
And to be frank... I am far more productive in my business as well. Every desk is surround now...
 
This is coming from a fellow EVGA member that was one of the first ones to go surround. Brad and a few others did it before I did with adapters/kits. I did not try it until ATI/AMD first released it in their high end GPU. And I had to try it.
 
I am still running the 347.52 Driver... And as a reference... I average about 1000 hours of gaming a year.

I've been running surround for a few years now and I love it. I'm running 3x1080p@120hz. I can't really say game compatibility is that bad, just use Flawless Widescreen or WSGF. I can't compare it to 21:9, because I've never used it. But I have considered adopting it, mostly for the 1440p aspect of it. Wouldn't mind a little more vertical space. Still, the dream is to some day get the horsepower for 3x1440p. It's also very practical for multi-tasking on the desktop.
 
 
If I can get Mario 64 running, you can get most things running:

What kind of frame rates are you getting from a single card?

In an attempt to add to this thread, and not turn this into a 144Hz is superior blah blah blah, per the OP's request... I hope the following is taken as thoughts, not feather fluffing...
 
Most should know now that the Hz measurement (In its true measurement not the fake 240Hz garbage we see a lot in "Marketing" ploys) of the maximum a monitor can display FPS without what some call "Tearing" in certain situations.
 
In all reality, I like to simplify this... I want a monitor or a set of monitors that allow me "Fluid" gaming from 70-100FPS. I cannot get this on a 60Hz monitor. This is not to be confused with the GPU not having the HP to make it happen. Or pixel generation.
 
You see... I learned in my Hifi audio days, that if one want "Clear/full" music. One must be smart about who is reporting the components abilities (Signal to noise ratios or THD, frequency bandwidth, class and RMS per channel) and be knowledgeable about what those numbers really mean in the real world. And from all of the learing/life mistake/etc. I live by the following...
 
In order to have full life like music without distortion, and a "Party" level. One must build a desired kit that will only get to about 70% of its max capacity in the "Party" environment. In other words...
 
If I need 500w speakers/amps ect, I buy 700-800w so that I never hit the distortion at the levels I want the sound to be at. I never max out the kit.
 
This is how I build my computers... Do I need a 1200w power supply? no. But say I do need about 800w at full tilt. So you will not see me buy a 850w PSU because the system only needs 800w. You will see me get the 1100-1200w units...
 
And thus... Why I will not ever go back to the 60Hz world. It irritates the daylights out of me when I spent so much (Time/effort/$$) to build a system, just to throw it away at the output point. I have repeatedly shown folks in my home and business the difference with 60Hz and 120Hz. For some, that 5% of the time it is clear as day noticeable, it is not worth the cost to go to 120Hz. There is nothing wrong with that. But it is for me. And why I am waiting for a 42"  120Hz 3840x2160 ish monitor or something similar before I spend another dime on the "Visual" part of the system.
 
This is also why I buy all my cable from BlueJeansCable. Hi quality, superior to most off the shelf garbage...
