Acer B286HK 28" 4k Monitor a good buy for me?

[Fate]

So I'm planning to update my monitor. I really love everything about 4k monitors, especially the screen real-estate. 

The plan would be to buy this monitor now, and in a few months, buy a 970/390/290. I know my little 270 isn't going to really run most games at 4k (I'd just turn the resolution to 1080p for demanding games), but that's not the main reason I wanted to buy it. I wanted to buy it for the productivity/look/portability*/and it's just in general a huge upgrade from my current 24 inch 1080p TN display. 

 

What do you guys think? Good buy for $350 or no? The other choice right now would be a 970/290, but I kinda wanted to wait and see what the 390 has to offer.  ($350 is my absolute max budget)

 

Thanks

 

 

*- It's more portable than what I have because I travel a decent amount and putting one monitor in the car is much easier than two.
