No. System Requirements for this webcam include: "800MHz or faster PowerPC G4 or G5 or Intel Core processor".
That means _800 MHz or faster for G4 Macs only_. *Any G5 or iNtel Mac will work*.

... mine is only 600 MHz.
Something is amiss here. Your system info shows that you are using
iMac G5. However, there are no 600 MHz G5 iMacs.
As shown in Apple's specifications:
http://support.apple.com/specs/#imac , the slowest G5 iMacs is 1 GHz. You can determine your actual processor info by using your Mac's
> About This Macmenu command.
Notwithstanding my confusion, any G5 iMac using Mac OS X 10.4.11 or later can use the Logitech QuickCam Vision Pro without iChatUSBCam or any other software additions.
However, if
> About This Mac shows you that you have a 600 Mhz processor, you are probably correct that the webcam will not work with your Mac.
