Hey gang, I probably should know the answer to this, but it's always good to hear what the MacRumors PhotoCrew thinks I'm getting a 2.66 Mac Pro (and will up the RAM when I can afford it.) The only intense/pro application that I use is Aperture. I know FCP doesn't use very much of the GPU (as compared to RAM and CPU) but I'm not sure about Aperture. Do you think there will be a noticeable difference on the X1900XT? (I'm using a 30" display if that actually makes a difference -- I assume dual-link is the same for all vidcards.) Or does anyone know if Aperture is GPU accelerated?
