So I am not too familiar with all the lingo when it comes to processors, I know enough to get me by, but there are a few questions I have...and possibly other MR users have as well. First things first, it is rumored we will see a refresh of MBPs in about 3 months which may sport a quad core processor. Right now the current lineup for the MBP is the Core 2 Duo, which is also the same processor I have in my Alu iMac. I have the 2.8GHz. I just want to know: what are the performance gains between a Core 2 Duo and a quad core? What is the difference between i5 and i7?? If there is anymore information you think I should know / forgot to mention, do tell!
