At present I'm using this machine with 10GB of RAM: Model Name: Mac Pro Model Identifier: MacPro3,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 2.8 GHz Number Of Processors: 2 Total Number Of Cores: 8 almost exclusively for LightRoom 3.5 editing of large (Canon 5DMkII) RAW files. Seems like this may be more machine than I need, overall, for this purpose. SO I'm thinking of doing a trade in on the new Mini Server, maxed out with RAM and processor. The MacPro works great. But I'm wondering how close to this performance I might get with the new Mini Server, a maxed-out version. Does anyone know how these two machines might compare for LR3 processing of large RAW files?
