I was just given a Mac Pro by a friend who's office was being cleared out. I don't have a display lying around to hook it up to so I can't check the specs. It's serial number is CK7421WGZNZ and after checking online and the tag printed on the machine I thought I had a good idea of what its specifications are, 2006 2.66GHz quad Mac Pro - however looking inside it has a single length ATI card rather than the NVIDIA GeForce 7300 GT expected from the specs. Any idea what this ATI card could be? I'm guessing there could be some other changes as I can't honestly believe someone was still working on it in 2014 with just 1GB RAM??
