Can someone please explain why all questions and most configs have poeple choosing the 2.66 8 core over 2.26 8 core. Obviously, the 2.66 is faster, but how much? I've seen the Barefeats test and all, but it's not that clear to me. I want a Mac Pro for video editing. Going to be using Adobe Premiere, since I am very familiar with the program over Final Cut. I am stuck on choosing the Quad 2.93 or the 8 2.26. But every time I read reviews or speed test, the 2.66 8 Core is discussed. Is 2.26 8 core no good? Should I go with 2.93 Quad? I will also be using Photoshop, but mainly Premiere for video editing.
