That looks like a Avermedia Purity3D 500, It has a hardware encoder for PVR functions. Analog recording is actually a thing in some circles usually for things like laserdisc restoration or old VHS. Most people want a card that can do uncompressed analog recording with a 3d comb filter in a program like virtual dub.

Without really trying to research that card my immediate impression is this card can't do that but if you find out it can it could be valuable. If it doesn't though its value is really low unless it is capable of tuning clearQAM. Then it could still be usefull for someone that has access to unencrypted TV broadcasts or if thier cable company has unencrypted digital channels. If this scenario isn't true than the card really doesn't have much value in 2018. As all you are left with is PVR functions for analog cable TV which may still be a thing somone but I think it's not really that wanted.
