I am running Aperture on an aging 1.25 G4 MDD. Not fast at all. With the release of the 8-Core Mac Pros, I'm wondering if anyone who's using Aperture has gone and gotten themselves an 8-Core at the Mac Stores yet and given it a shot? Will Aperture scale to 8-Cores well? I'm NOT going to pay an additional $1700USD for the extra cores (albiet at 3.0ghz) if there's going to be a 5% speed bump. In that case I'm thinking that throwing more memory, and a better graphics card in the Quad Mac Pro would do the trick better. So with the new release in mind, what's the most sane Mac Pro configuration for making Aperture usable, but not going overkill at the same time. I'm shooting with a D200, so I'm producing 10.2mp RAW files if that matters. EDIT: The NVidia Quattro 4500 is a little cheaper than the processor upgrade... I know Aperture is very video card dependant, but does the 4500 make more sense than the 8-Core? I use the machine almost soley Logic 7 and Aperture. If it can run those well, I'm happy no matter what.
