For just streaming and transcoding movies/video, I would suggest any of the following. They are all sub 100 dollar cards, Potentially passively cooled, and low profile options are available. they are also recent enough to have modern transcode/decode options for movie/video watching.
GeForce GT 1030
Nvidia GTX 1050 mini
AMD RX 540/550
Even the AMD Radeon RX 5300 that is on the map for release later this year.
