Ok so i am currently in the market for another mac. I am a home user BUT i love power...I may or may not ever use it but would like to have the option if it is there.. I pretty much do the following.... Internet usage import 720p-1080p content from my digital camera into iMovie and make small home movies Stream 720p and 1080p movies via PS3 Media Server to my LCD TV ( i believe PS3 Media Server relies on CPU usage for encoding the movies ) Use garage band for recording guitar playing and doodling Some mild gaming ( nothing hardcore ) As i said, i am pretty much just a home user, but i am still unsure as to which machine would offer more power. I understand that the Mac Pro offers me the options for upgrades and add-ons in the future ( ram, HD, Video cards, etc ) I understand that with the iMac i am sort of limited BUT i do get a nice 27" monitor built in. I really dont plan on upgrading anything, Once i order either rig, i plan on sticking to whats stock in it. Unless i go with a Mac Pro i might in the future toss in another HD. THe Mac Pro seems more future proof then the iMac. I am just really curious about the power and CPUs in the 2. Which one offers more benefits/power/etc.... One 3.2GHz Quad-Core Xeon Nehalem vs 2.93GHz Quad-Core i7 I will be going with 8gb of ram regardless of the system i choose. Lets say for instance i am doing the following...... Burning a DVD, Listening to iTunes, surfing the net and streaming a 1080p movie to my LCD...Will both CPUs be equal in power? What about if i imported a 30min long 1080p video from my digital camcorder, edited it in iMovie and then saved it as a movie? Which system would do it quicker?
