My 2.5 Quad is for sale on craigslist, and a prospective buyer has e-mailed me this: "I might be interested in your PowerMac. I currently use a Mac Book Pro (2.8ghz, Intel Core 2 Duo, 4gb ram) for graphic editing (photoshop, indesign, dreamweaver, etc). Can you tell me if your machine will be quicker? Thanks!" Will the Quad be a good desktop substitute for the kind of work he does? I want to give him an honest answer, not an "Of course! When can you come pick it up?" without knowing for sure. I told him that the Quad is still very strong for that type of work, and was comparable to Macs sold even as late as 2-3 years ago in raw power. Thanks all.
