I might be dumb, and I'm sure I'm not the first to have noticed this (use the search! akm3 you jerk!) but... Is there any possible reason why any sane person would purchase any of the mac pro refurbs in the apple refurb store, instead of a new 2.8 4 or 8 core system? My understanding: Early 2008: Better video card, better cpu, lower power, quieter, cooler, more performance, cheaper. Pre 2008: Cheaper to upgrade the RAM Am I missing something obvious, or is Apple's Mac Pro refurb pricing completely insane? What would be reasonable for the old 4-core units? About $1800?
