But unless you're on a T-1 or better, I still don't think the better frame rate of a
digitizing card is going to get you anything. The bottleneck is in the bandwidth, not the
CPU...I've run both the QuickCam and the Hi-8 on my system (840AV connected to a T-1) and
found that the QuickCam gives better overall performance in terms of cost, ease of use,
functionality, and image quality, etc.
