I'm in a little bit of a pickle. I've recently started working in a computer store and I'm being teased daily by the MacBook Pros with i5s and i7s I have an old MacBook with a 1.83 core 2 duo and an iMac with a 3.06 core 2 duo. I use them for ProTools and music editing mostly. I was wondering, would it be worth my while to upgrade the ram on my iMac to 16gb or sell/trade/recycle the 2 of them and get a MacBook Pro??? Currently my MB is maxed with 2gb of ram and iMac has 4gb. Would 16gb of ram help to be up to par with an i7 MBP?? Thanks, Colin.
