Hey everyone. I'm in the market for a new Mac Pro for home use. Currently at work I'm using a 2 x 2.66 GHz Dual-Core Intel Xeon Mac Pro with 5 GB's of RAM. This system was purchased a few years ago. What I'd like to get for home is the brand new Mac Pro with one 2.66GHz Quad-Core Intel Xeon with 6 GB's of RAM. Can you guys please fill me in on the speed increase, if any? I guess "on paper" it looks just about the same to me, minus the extra GB of RAM, of course. I know very little about these Intel Xeon processors, so any information you could give me about the increase (if there is one) would be greatly appreciated. I'll be using my home system for (besides all basic tasks, email, web, music) A lot of Aperture, Photoshop, Final Cut, iMovie, etc. In short, is this a good system? Thanks in advance for any information that you could give me!
