I have an MSI GT 710 working with MythTV master in Fedora 27.  It works 
well with DVB-T2 (HD) and DVB-T recordings in the UK, but I think it 
won't do 4K.  IIRC it's using nVidia 395.  It's fanless.

I have also installed an ASUS GT 710, which I believe has faster memory, 
in another family box, but there it is running Windows 10 on a 2nd gen 
i3 for 'homework' and non-state-of-the-art games.

The GT 710 appears to be designed to fit the 'update' HTPC market.
