Mac Pro - Is Premier a Good Mac Pro?

i know there's you to pres out there that are doing it full time. Everything i've heard, it can handle it. I remember when the big 18 corpsima came out, and they were doing tests on premier. And whenever the reviews were doing premier, you could see only one of the cores, maybe one and a half, being unused. You use any other programm, it's maxing out the computer. Same idon like light room, when i was,. i was doing my mac pro review, and that’s when i discovered, like, aweight, light room doesn't use any of these cores at all.
