I am currently in the market for a New Laptop I am impressed by the noticeable difference between my very old MacBook and the New Macbook pros. Has anyone who bought the new 2011 MBP noticed any speed differences between older MBP and the newer ones seeing how Maya and a few other applications do not take advantage of all 4 cores? I have yet to find a Benchmark test for render speeds in both Maya and After effects? I also noticed there are concerns about overheating has anyone who runs render programs who have rendered for 8 or so hours at a time notices heat problems as well? I was looking at picking up the 15" MBP 2.2 with 128 ssd any help from other professionals would be great thanks.
