I've read that the new MBP's Sandy Bridge processors are much faster and more efficient than that of previous generations. With the highest end MBP being faster than some current gen Mac Pros. I'm curious how the newest low end 13 inch MBP compares to the low end 21.5 inch iMac that came out last year as far as processing power and speed. Let's say for Final Cut Pro editing. Is the low end MBP as/more/less powerful than the base 2010 iMac? Any thoughts?
