I have a Late 2006 MBP that came with a 1x1GB installed. I just recently decided to upgrade the RAM (I know should I should have done it right away, oh well). I ordered a 2GB stick from OWC that hasn't arrived yet. I know that I got the last MBP that couldn't address the full 4 GB and can only "see" 3.3GB, so my question is.... Is it worth spending the $50 for another 2GB to get the extra 300MB of RAM and the Dual-Channel speed boost? I am not a power user or anything, probably the most intensive task I do is run VMWare Fusion to do Quicken in Windows (the lone hold-out program that I haven't found a suitable replacement for!) I'm guessing it's not worth the other $50 but I'm just throwin' it out there to see if I'm wrong. Thanks.
