Been wondering if this is a good idea or not and I'm going to be moving soon which is why I'm thinking about this in the first place. My computer would be under the most strain for digital painting and photoshop crashes with some brushes even with 6GB.. so here are the specs: Mac Pro(What I have now) 2.66 GHz Quad-Core Intel Xeon (1 Processor) ATI Radeon HD 4870 512MB 6GB DDR3 1066MHz 80GB SSD Drive (Boot) 2X 1TB Drives in Raid 0 (Data) 2TB Time Machine 15" Macbook Pro (What I might switch to) 2.3 GHz Quad-Core Intel Core i7 Intel HD Graphics 3000/AMD Radeon HD 6750M 1GB DDR5 (is this right? it has both?) 8GB 1333MHz (Is it possible to get more ram somewhere else?) 128GB SSD Drive (Boot) ??? Maybe a Thunderbolt Drive for external? ??? Time Machine A bit hesitant to do this since I went from a 2007 Macbook Pro C2D to my Desktop but of course that was a noticeable difference in power.. hopefully this isnt that much of a difference or maybe even an increase.. So how do these 2 systems compare? Will I notice the difference in processor power? is there an external that would allow the speed of what I had before from my internals?
