Cheap Quadro card for my unraid box?

[widdefmh]

Looking for small graphics cards to put in my unraid-box, is Quadro cards a possibility?

I don't play games at all, so a gaming card is not needed. 

I run two OS:es at the same time on my server, Linux and Windows. 
I'm a developer so I develop on my computer, surf the web, 
some image editing in Photoshop and some video editing. Video editing is on hobby basis,
just edit my own recorded movies sometimes. I want to be able to see 4k movies 
without problems.

I saw a PNY Quadro P400 (or p620) 2GB for not so much money, can this card be a candidate for
my Unraid box? It supports 3 monitors with 4K@60Hz. 

What am I missing with such a card? 2GB feels small.. 
This card is quite small and will fit perfectly in my box..

Gaming cards has 4-8GB memory, and this only 2GB. 

 

Thanks in advance.
