A friend asked if I wanted to buy his MacPro 1,1 for a couple of hundred bucks. I'm curious if it would offer any significant performance gains over my current machine. Specs of the two are below: MacPro 1,1 Dual 2.0 GHz Xeon 12GB RAM 250GB 7,200rpm NVIDIA GeForce 7300 GT w/ 256 MB MacBook Pro 5,3 2.8GHz C2D 8GB RAM 512GB SSD NVIDIA GeForce 9600M GT w/ 512MB Primary Use Heavy CS5 use, some very light video editing, and everyday tasks. The MBP is serving me fine but I am beginning to reach the limits when working with large Photoshop and InDesign files. I know the MacPro 1,1 cannot run Lion and it's nearing the end of its official support but the increased max RAM and more ports are tempting. Any thoughts? Thanks!
