I'm a software developer looking for more real estate on my desktop.  I play occasional games, but not as much as I'd like.  My budget is at or around 1k.  I'm worried that if I get one that's too small, I'll end up having to zoom the text to even be able to read my source code.  If I get one that's too big, I'll end up with neck issues.  28 inches?  30 inches?  32 inches?  Something else?  I've got a GTX 1080, does it matter if it's a G-Sync monitor or V-Sync?I found this list of G-Sync 4k monitors, but the reviews are pretty sparse.  Any suggestions?
