Hi, I've got a 2008 MacBook 2.4GHz with 160GB HDD and 2GB RAM. I know it's not going to be lightning fast, but I wondered how best to speed things up as I can't afford a new computer. It fine for general use, runs Lion smoothly, web browsing, spotify, movies etc, but really struggles when I try to process my Canon 50D images in Aperture. Would I be best off buying more RAM, or a quicker HDD? I've been thinking about one of the seagate momentus XT hybrid things. I did end up with 1GB page outs after using aperture and photoshop on my last 30 photos, but I don't know which would be the best upgrade. Any thoughts?
