bought a D90 on sunday, the sales person has throw in a 2G card and it's only got a 45X rating.
So I was testing the 720p video and burst shots, when playing back the video on computer it's all laggy and the burst shots felt like there's a bottleneck somewhere.
i'm guessing the card is too slow for the camera and can't keep up. so i'm wondering what speed rating do i need that can handle the 720p video and burst shots on a D90??
i've notice some ratings comes in numbers like 45X, 200X and some comes in class, like class 6, class 10.
so what are you guys(D90 owners) using?
