Specs and demos of Aperture look amazing. Seeing the real application in action will no doubt be the only way to REALLY know its hardware requirements (we'll see what machines it's loaded on in Apple Stores, for example). I have a first generation dual G5 1.8 GHz. The graphics card is an nVidia GeForce FX 5200. On Apple's website it says that the FX 5200 "ultra" supports Core Image. Is that a different card? Thanks so much, Jim Robertson --
