I'm not familiar with the Creative 4000 Pro. Do you mean the Logitech Quickcam
4000 Pro? If so, then you did something wrong. The 740K and the QC4000 use the
same sensor and the same chipset. The hardware gains are set slightly
differently, but that can be compensated for programmatically. For good results
you don't want to use either near maximum gain anyway.

I've tried both side-by-side for astronomical imaging. There is absolutely no
difference in performance.
