i have a macpro3,1 with dual 2.8 quads and 8gb of ram. i haven't upgraded the GPU and i am rethinking that. my MBP late2008 with dual GPU is running just as quick as the mac pro....... my mac pro is an editing machine only. i have photoshop, lightroom and illustrator. its a good machine, but i know it can do more. a any help would be greatly appreciated.
