If you order an ATI 9800 Mac Special Edition video card for your G5, you may be confused when page 11 of the manual clearly states the card must be connected to the G5's internal power supply and to use the included cable to Y the power from the optical drive.
However, the cable is missing from the package, and ATI knows nothing about anything as usual with a big company
The truth is, the manual is wrong, extra power is not needed, just pop the card in and you're good to go.
I did some fps tests between the stock card and the 9800, I will post as soon as I get time. It is an improvement, but not as much as I would have thought!
