I'm considering upgrading my MBP 13" (2010) to the latest MBP 13" (2012). I have a few quick questions: Going from a C2D processor to a Core-i7, how much of a boost can I expect from this? (50%, 100%, 200%) I envision it to be a dramatic boost but would like some empirical evidence as well. Has anyone swapped in an opti-bay caddy to replace the optical drive in the new MBP13? What speed does the SATA connection for the DVD-drive work off of? Thanks in advance!
