Hi all I'm going to buy a Mac Pro. Fully loaded. I'm just getting stuck at the CPU options. I do music production as well as 3D rendering along with a little BootCamp gaming including the Dolphin (Wii) emulator. I'm trying to decided between the 8-core and 6-core model. While multiple cores are important for 3D and music work, I'm also interested in good old-fashioned clock speed for single/dual core apps like Dolphin and PC gaming. The 6-core runs at 3.5GHz with a turbo boost to 3.9GHz. The 8-core runs at 3.0GHz but also has a turbo boost to 3.9GHz. As far as I can tell, there's very little difference between the 3.0GHz and 3.5GHz processors. Sure, the marketing says it's 500MHz but looking at the turbo boost and core scaling information, it looks as if they're almost identical for single core applications because of the 3.9GHz turbo boost on both CPUs.
