Many old PCIe GPUs had noisy fans and drew tons of power though. It's not the whole story.
You can, however, buy something like a passively cooled Nvidia GT 710 for really cheap, which I think is what you're getting at.

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!
