I'm looking for the cheapest and used GPU with HDMI and DVI / VGA port. I would connect it to the TV and a monitor. I won't game on it, only 480p, 720p and rarely 1080p movies through Plex.
I have enough internet for it.

What is the minimum requirement for 1080p playback? I thought about a nvidia NVS 310 and a GT 620 and the MSI R6570 1GB model.

Thank you for the answers! :D
 
Thats too old, wouldnt even try to bother.
Give me your local sites or where you buy things off , ill link it here and specify your budget.
Oh and sorry for saying that I dont trust MSI R6570.
I think the MSI R6570 and GT 620 should handle very well at 720P and 1080P with H.265 encoding if the movies will stutter.
