Jules,
Apple strongly recommends the 1900 card as well so your inclination is correct. For those still looking for an overview of Studio 2 here is a good one:

Here is an exerpt from the article regarding the smooth cam
"The background process window updates to show you how many clips are currently in the queue for processing. Once the clip has been analyzed it does not have to be analyzed again. The analysis data is stored on your hard drive. By default, this data file is stored in the same directory as the media file. To achieve optimal results from the filter, make sure to set in and out point for the portion of the clip you want to stabilize. As I mentioned, the entire media file must be analyzed, but the results of the filter will only be applied to the portion of the clip between the in and out points. If your clip has already been edited into the timeline, in and out points will most likely have already been established. However, clips you plan on analyzing in the Browser may or may not have in and out points sets and you will want to set them before analyzing."
