I'm planning on buying a webcam and have narrowed it down to:
Logitech Quickcam Communicate Deluxe £20.89
Logitech Quickcam Communicate STX £24.99
Microsoft Lifecam VX 6000 £28.95
My computer is not new, has an athlon 1.67GHz and 512MB Ram, I'll be using the cam for Windows Live Messenger, and video calls, and mainly in dim lighting, if anyone can help me with this query I'd be very grateful, thanks in advance.
