The main way to tell which expansion card is the video card is to look at the plug. If it has a VGA socket, a display port socket, HDMI, etc., then you will know it is a video card. You may identify some of the chips on the card as being RAM, or you might find a fan on it, but these features are not exclusive to video cards. If that is the place where you plug your monitor, then it is a video card, unless of course you are plugging directly into the motherboard.
