Hi Robert, I've got a passively cooled R7 250E (Cap Verde Pro) with 2 GB video RAM (probably identical to the GDDR5 version of the Radeon HD 7750). All technical details can be found in Wikipedia: https://en.wikipedia.org/wiki/Radeon_HD_7000_series https://en.wikipedia.org/wiki/Radeon_Rx_200_series It is a GCN 1st gen. card and supported by the xf86-video-amdgpu driver and the DRM kmods and libva drivers. I would not get a lower end card, they are neither cheaper nor more power= efficient (idle power of 10 W, 50 W max., allowing for a very silent fan or even passive cooling in a case with forced airflow). The HD 7790 is already GCN 2nd gen., but probably harder to get, and at $70 about twice as expensive as a HD 7750 on eBay. All R5 240 and higher cards should work as well (R5 220/230/235 are Terascale cards). The only drawback compared to a modern card is raw performance (but the 7750 is already faster than today's typical on-chip VGAs) and lack of HW decoding of modern video codecs like VP9.
