I am dabbling in object identification in images and videos. I am not much of programmer so just using other peoples work. I would like to accelerate it a little bit with a GPU but remain low power and possibly fit in one of my low power 1U servers that are C2558 or C3558. Any recommendations? Nvidia is most supported for these tasks? Low power, inexpensive model, used is fine too? I was thinking even lower end model will be a lot faster than any CPU? Thank you.
