Upgrade or buy new pc

[Anonymous]

I have question about my desktop I have this desktop:

CPU: i7 3770K - 3.4GHz RAM: 16G - 1600 Motherboard: p8h77-m pro Graphic Card: AMD Radeon R9 200 Series (3GB - GDDr5)

Monitor: LG IPS234

I'm planning to upgrade my desktop to enable 4K I'm not a gamer and i've never been played any game. I'm a programmer and I want to watch 4K videos I checked and I found that I should change my GPU and Monitor I like to buy two LG-27UD68 (DUAL Monitor)

and I like to watch 4K videos without any problem (60 fps)

so my questions are :

1- do you suggest to build a new PC or upgrade my current PC?

2- if I want to upgrade my pc then what about the GPU ? I want to spend minimum amount of money that I can. and I prefer IPS LED monitors thanks

Upgrade 

I7-7700 is the current i7's you'll see in the new PC's 

Here is a list of all the Certified Cards:

However, I have a 1060 and 1070 Nvidia GTX and they work great

32 bg of Ram is what I'd recommend if you're doing small models, no calc's you can squeak by with 16 gbs

Get enough Disk space ...everyone wants a SSD, but end up with a 256 and running out of space fast.

You can find just as good monitors by LG for cheaper.

I have dual 

LG - 29" IPS LED WFHD 21:9 UltraWide FreeSync Monitor

Cheaper for both of these, than 1 of the 4k you listed
