I currently have a 2008 mac pro with two 2.8 ghz Xeons, 4 1TB drives, 4770 graphics card,etc. I use to use it exclusively to do pro-tools and final cut pro work but now I mostly do video work. IE one to three cameras in a seminar or church setting with 1 to 4 hours of video. Pro-tools is just a hobby. I almost never use the mac pro unless I'm rendering files as I have a 17" I7 macbook pro with 16gb of ram and 2 1TB SSD drives. I was thinking of upgrading the mac pro to the new mac pro with 6 or 8 cores. Is there a huge difference in performance between the 6 and 8 core? Has anyone ever tested a quad core I7 mac mini versus a 2008 mac pro in terms of FCP / video rendering? A buddy got rid of his single four core 2.8ghz mac pro and opted for a new mac mini 2.6 quad core I7, with 16BG of memory and a internal 1TB SSD drive. He spent about 1200 using non-Apple parts but claims its still faster than his 2008 mac pro. Any thoughts?
