A good web cam (a good whatever in fact) is one that can cover your needs. So my next question is what do you intend to do with it? How important is video quality and sound quality? A resolution of 320x240 should more than enough for most people, it won't be impressive, but you should be able to work-out fine details if the bandwidth is sufficient. As for sound, if you want good quality, I suggest you get a separate headset unit or at least a microphone. Otherwise, what is built-in does the job, but don't expect much from it.
