I've searched the board, and haven't found an answer to this specific question, so I thought I would ask it. I'm curious as to which processor would be better for my uses, the 2.7ghz i7 duo, or the 2.0ghz i7 quad? I use Sibelius, Logic, Ableton Live, Reason, etc., and I haven't been able to find any information as to whether or not these programs would benefit from 4 cores? I've seen benchmark data from certain applications and processes that say the duo is better for certain things, but I'm unclear as to where to make that distinction? Anyone have any ideas? Thank you for your help.
