Graphics cards capable of pixel-level programming deliver the best performance. But Core Image automatically scales as appropriate for systems with older graphics cards, for compatibility with any Tiger-compatible Mac. Supported graphics cards: ▪ ATI Radeon 9800 XT ▪ ATI Radeon 9800 Pro ▪ ATI Radeon 9700 Pro ▪ ATI Radeon 9600 XT ▪ ATI Radeon 9600 Pro ▪ ATI Mobility Radeon 9700 ▪ ATI Mobility Radeon 9600 ▪ NVIDIA GeForceFX Go 5200 ▪ NVIDIA GeForceFX 5200 Ultra These cards are available in today’s PowerBooks, Power Mac G5s and both the 17-inch and 20-inch iMac." (Leander has quoted some sections of this before) That means that the previous revision of Powermacs (when the 15" Aluminum was released) will fully support Core Image, but the first generation of 12" and 17" powerbook will not. I'm curious about what they mean by "scaling" also. Hopefully with a GeForce4 440 Go and 64MB of VRAM, it will still run reasonably well. Ha, and I was SURE my 17" powerbook would be fully supportive of Apple's new technologies (sans 64-bit stuff) for the length of my AppleCare. I guess it's good that Apple is able to make such great leaps in software where only the newest hardware can fully take advantage of. Benn
