Hello,

I have a question. We have this card in our firm that was bought some 2, 3 years ago for reasons unknown and wasn't used at all. But since it was very expensive maybe it's still powerful compared to today's graphic cards. Now I couldn't find anything online about the card specs nor does it says anything on the box. It just says that it support all major editing software.

I work in premiere pro CS6 and have a GTX 650 card with 1GB GDDR5 memory. Is the DeckLink card comparable to this (is it faster?) and should I even bother with it?

Its not a replacement to your existing video card. It just provides a different signal that is compatible with broadcast monitors. It won't improve the performance of your system. Only give you more connection options.
