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
