Refurbished store lists 2.93 quad @ $2550. If I complete it I get this: mac 2550 memory 3x4gb 870 ssd Intel 160gb 600 matrox hd 550 plus 2x1TB stripe for data all together for ~$4700 2.93 Octo is $2500 more @2.93. My thinking is that most apps today benefit from faster core rather then from their quantity. The selected few (FCP?) might use all cores (?) but what would be real life difference in running FCP and AE on 12GB quad vs. octo? Let's leave encoding out of this, I'd use matrox HD compressor for that. Would setup above be ok?
