Just my 2c. I daily drive a GT710 passively cooled from MSI, it has a HDMI DVI-D and a VGA port. One of the newer GT710 models from ASUS has 4xHDMI.

Displayport quality is miles ahead compared to the above on the same monitor. (I daily drive 2x Dell P2419H)

If you are going for a multi monitor build then the GT710 is a bad choice if you care about quality.

I would suggest something along the lines of a proper GPU which has a silent mode in which fans do not run unless they are under load. IIRC Asus STRIX cards and Zotac cards had the feature and I am sure other vendors also have something similar.

Ofcourse the best option would be to find a motherboard with a ton of displayport connections, but I did not find any!
