According to my sources (and I have a detailed answer on SU on the subject, including a handy graph and links to a spreadsheet) - 27" is *pretty" darned close to the sweetspot for PC use.
I game on a 980TI at that resolution (which is fine) but I've driven 4k60 off much older/less high end video cards. I don't use gsync (which is mainly for gaming) and ...
I would say that it is better to get an adjustable VESA stand on Amazon, than to actively search out for a monitor with an adjustable stand on it.

Ultimately I did buy the Dell U2718Q, when it was on sale.

I use two Samsung UE590Ds, and would recommend 4k for both programming and games. I run Visual Studio and a large array of steam games.

If you move objects from one screen to another or just look from one to another, you will get serious headaches. I have this problem with a 1920x1200 main monitor and a 1280x720 second monitor.
On the other side, gaming or not, your setup will ...
If you are interested in modern stuff, you won't have a problem. Scaling issues only occur with dated software. So, as long as you aren't trying to run Battlefield 1942 you should be able to enjoy your UHD display.

I'd recommend the GeForce GT 710, a fairly new card aimed at HTPCs as a replacement to integrated graphics. It supports up to 4096x2160 resolution, has a very low profile, and is plenty fast for any video viewing or streaming.
The particular model I linked not passive, but should be more than silent enough, especially over the sound anything you're watching....
