Quick question... I just got a new iMac (3.4GHz processor) with 16GB of RAM. I noticed recently that when moving large amounts of files (ie: 20,000 or so) that I sometimes get the spinning beach ball. When I click on a different Finder window to do something there while the files are transferring the Finder window I just clicked on doesn't become active for about 5-10 seconds (all the while the beach ball is spinning). So, here's my question...is this lag a function of not enough RAM, or a function of an FSB bottleneck? Thanks, J.
