Anyone else here read the system requirements for Core Image? It seems a little steep but it makes sense since that it very demanding of the GPU. I wonder what Apple means by "The performance gains and features supported by Core Image ultimately depend on the graphics card. 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." Does that mean that Core Image will still run (just without some of the bells and whistles) on the Radeon 9000 in the last revision of the Tis or does it mean it will be like Quartz Extreme and cut off on any graphics cards that doesn't meet it's requirements? I also wonder where Apple is going to draw the compatibility line this time. In Panther they dropped all no USB native Macs. Anyone heard anything about Tiger's minimum system requirements?
