That's why it's a bad comparison. You mention "CPU-intensive", but Aperture is particularly GPU-intensive. In his original post Matt made this requirement for Aperture performance: "when straightening a photo I'm willing to slow down and be more deliberate, but not willing to lose track of when the computer has caught up to my input". Therefore he needs to look at GPU before he looks at CPU. Stroller.
