Hello! I'm just not sure about the timeline of releases over the last few years. Wondering if it's worth buying an older machine that's been offered to me. Here are the specs: 2 x 2.66 dual core intel xeon 10 gb ram 320 & 500 gb hard drives Ati Radeon HD 3870 Wireless G 2x e-sara ports non hot swap He said he purchased it in 2008 and it is a "mac pro 1.1". In the other forum people talk very highly of the 2008... Is this machine valued at $1400. Is it worth it? Thank you!
