Upgrades with Photography in mind--- I was considering getting a new iMac after my hard drive failed, but went and replaced the HD with a SSD on a whim. Now I am simply trying to optimize my entire system with the end goal being a faster photography workflow using mainly Aperture 3 and some occasional Photoshop CS4. Questions- - Will going from 4GB to 6GB give me a noticeable speed boost while using aperture? - I plan on buying a new hard drive as my current one is already 2/3 full. I currently have my aperture 3 library on a 1.5TB usb2.0 hard drive will moving the library to a FW800 hard drive increase speed in aperture? Thanks!
