Just a couple of days ago, I inserted the above video card into a G4 533 Mhz system.
I'm pleased to report everything runs fine so far. At the moment, I'm connecting it to a 15" CRT via an Apple DVI-VGA dongle.
Decided to post in this section as it seemed a little empty. Also, maybe there may be like-minded people who wants to decide to get such a card. It is great enough to support Core Image and affordable enough to warrant spending such a budget to extend the life of one's aging machine.
Detail Specs (fr ATIccelerator II)
Processor - 365 MHz
Memory - 295 Mhz
Radeon 9600 Pro (aka ATY, RV350 as seen in ASP)
