From what I remember the devs saying, the capacity does not matter as much as the speed of the card. A class 6 will work a lot better than a class 2, I use both (8GB each). The class 6 is my main one, the class 2 I put the new releases on to try them and make sure various things work. If I don't have problems, other than force-close/wait messages, I put it on the class 6 and that usually gets rid of most of those.
