The 8 Core 3.2 Ghz one is a tiny bit better then the worst 4.1 CPU Quad 2.66 Ghz
At single stream maybe. With an application like Premiere Pro that uses all 8 cores then the 8 core is much better. I am guessing from your handle & the spec of the Mac Pro in your .sig that your interest is gaming & not professional video editing.
The OP has been asking for opinions about native OS X video editing on a 2008 8-core 3,1 Mac Pro. Gaming performance or ease of use of bootcamp or whatever is irrelevant. Every other owner & user of a 3,1 who has posted in this thread has said what a great machine it is especially for video editing. It's not in dispute that it's possible to upgrade a 4-core 4,1 more but for the money the 8-core 3,1 is a better buy for use TODAY. It looks like all the posters dissing the 8-core 3,1 neither own one nor do video editing so their prejudiced opinions are purely theoretical. I don't own a 4,1 or a 5,1 but I don't need to as I know that the 8-core 3,1 is a great workhorse for video editing.
