I want to try my luck on trying to a gamer on Twitch, I know there are people who are making a living by broadcasting their videogame playthroughs live on twitch. I heard that I need to install a capture card so I will be able to broadtcast my game footages. I wanted to know what are the most popular brand of capture cards? Is this something I can easily mount on my PC or is it something like a Ram card or graphics card that can only be installed by a professional. What is the usual price ranges of capture cards?
