Me again.
First off, what peripherals have you got? How much space have you got? What resolution do you want? You could get a 1080p monitor with eleven millionty refresh rates or a 1440p with a good refresh rate. You could also go 4k with a slower refresh rate but this will melt your face when editing. Imagine all your apps, all at once, on one massive screen.
Personally I've got a Samsung 32" 1440p screen that cost summat like £380 and it is just gorgeous. 32" might sound large but once your'e used to it, there's no going back.
When you say green, do you mean the colour or Nvidia?
We can build it at mine if you like. I'll just hafta push all my Lego aside
