My guess would be that the problem is in the drivers, not the hardware. Maybe your webcam installs additional processes that take unnecessary cpu time? (I heard something about snapdetect processes) Oh and for the record, I use Logitech Quickcam Pro 5000 and I only get 1-3% jump in the cpu usage. But if you google around, you'll see that some people have managed to get 100% usage with this webcam. All the more reason to think that it's about flawed drivers/software rather than hardware. Also the cpu hit might be linked to the RightLight (tm) -type of software that evaluates the image stream and adjusts the controls to get the "best" picture out of your webcam. If your inteded usage is Freetrack, then you're going to disable these features anyways.
