Which webcam should I invest in?

[matrix86]

I’m curious as to what you would suggest. The Logitech Quickcam Ultravision or the HD Pro C910/ My current system is a Pentium 4 3gHz, 2GB Ram, running WinXP Pro. It’s probably going to be no less than a year before I’m able to build my i7 system, but I would like something that’ll be better than my $30 Microsoft web cam. Just not sure if I should even bother with a new high tech cam or not. But if so, which of the two would be best? I'm just so tired of my current crappy cam.
I plan to use it for skyping as well as regular video recording. Thanks.

The $50 Logitech will do fine I imagine, but the $74 Hi-Def video cam could be better for Skype if your internet connection speed is fast
