I am in the market for a new MBP. My budget is around $2000 (could go higher, could go lower... and this is without AppleCare. I plan on buying that a couple of months later). But obviously, the more money I save can go toward other things such as new studio monitors I get the full education discount, or a friend of mine at the Apple Store offered me one of his friends and family discounts. This will mainly be a Logic Pro machine, but also do bootcamp because of some of my old audio programs that are Windows based. I will be using it for multitracking (HD speed), synths (CPU/RAM) and live performance. My question is how much faster are the new i5 and i7 processors. There are several early/mid 2010 MBPs on craigslist that would be the cheapest option, but is the i5/i7 worth the extra $400-$500? Also, how is the speed difference between the i5 and i7. Noticeable for CPU intensive operations? Worth the extra price? Thanks for the help in advance!
