Thanks for your response once again. All of this discussion has gotten me back on the forums and doing research lol. I have been looking a lot closer at the 21:9 monitors since I posted on here. I do however disagree with a few points you made (I could easily be wrong, for me this is all reviews and hearsay, the only thing I have tried for myself would have to be the Gsync, and the basic ultrawide, not the 1440p).
I have herd that the ultrawide is the way to go for immersion, which makes sense especially because people are worried about the frame rates on the 4k monitors (especially those that only have one card, 4k wants a minimum of 4gb of video ram, 8 to be safe). Waiting for a higher Hz monitor is not applicable for me because from what I hear they have reached the potential for data transfer using the display ports and cables currently available. So having a faster refresh rate for anything over 1440p is not possible. Only so much data can be pushed at one time.
* As a side note, there are a lot of articles out there stating that producing the 1440p image at 144hz is very taxing on your GPU's even more so then 4k at 60hz. it has something to do with rewriting that much data on the screen that quickly. Either way you look at it you need a beast of a computer to run both.*
This leads me into the ultrawide, Gsync, and gaming. I have read that most games are not supported and in order to get them to work at 21:9 you have to download a third party program to get them to run. This of course is not a problem but not what you stated before (again I could be wrong, its hearsay), even with the program, I have also herd that not everything will work and even if it does the UI HUD, as you stated, will not look right.
Gsync, is amazing, I have used it. Apparently it is such a big deal that Radeon is making its own version, and companies are trying to make cords and other peripherals that do the same thing. From what I gather you don't notice a huge impact from it UNLESS you are gaming at 4k. The idea behind the technology is the same as Vsync, as you stated, except it is not virtual, it actually is syncing the GPU and monitor (Yes in this case it would be at 60hz or 60fps, which is fine for my gaming needs on anything except Battlefield 4, which as I said before I already have 1080p 144hz monitor for that.). This technology gives us the ability to play previously unplayable 4k games, by getting rid of screen splitting and dragging. With all of that and the fact that the ultrawide is still only sitting at 60Hz anyhow, i still do not see much of a reason going with the ultrawide.
For productivity and screen real-estate the increased resolution is supposed to be phenomenal on both of the products. You do get a little more with the ultrawide, but honestly it is not much. This leads me into a uniformity issue on my desk (yes, i know its stupid), right now I have the Acer XB270H which is the exact same design, size (I think its an inch bigger in the screen) and shape as the 4k Acer. While the Ultrawide does look great, i'm not even sure it will fit on my current desk, and with the inability to rotate and lift the monitor I feel I would get overly frustrated with placement.
I also wanted to point out that the Acer 4k monitor uses Twisted Nematic Film (TN Film) as a screen (people hate and love it) this does however give it an incredible 1ms response time and decent viewing angles. The Ultrawide uses IPS and sits at 5ms response (not a big deal, just not designed for gaming)
For movies, I do like the point that theaters use panoramic view, but I don't see that as a massive selling point (for 200+$ more). I don't usually download things under 2 GB especially if its movie length. For instance I could have less then 30 movies in a folder that is over 145gb.
So for now, I think I am going to go with the acer 4k monitor. It's a big choice for me, especially since I wont be able to get anything else for my computer for awhile. If you have any other input or noticed I was wrong about something please let me know. It will still be at least a week and a half before I order the monitor.
This is a good link that gives a good rundown on the 4k monitor I found later last night. This person has almost the exact same setup I do. He is running an older cpu but the same GPU setup.

He also goes onto explain why Gsync might be the best thing for computers for awhile. He also states he has officially switched from the ROG Swift to the Acer 4k for sheer graphic beauty , it did take a few hours to get used to the decrease in frame rate (144 to 60) but after he got used to it he says it was great.
If you do have any other input let me know what you have and use.
Do you have a 4k monitor?
does it have Gsync?
do you have the 21:9 WQHD and a 4k?
or is what you have said hearsay as well?
