We have an older 2008 Mac Pro 2.66 quad core with 6 GB of Ram. My wife deals with lots of very large RAW images and is always complaining that this machine is very slow. All the images are on a 3 TB RAID 5 Storage connected by Esata. She is running Snow Leopard, PhotoShop CS5 and the latest LightRoom.
Are the new machines that much faster and what would you recommend. Budget isnt a concern.
