I apologize if this has been answered before (I looked through some threads and couldn't find the answer) or if this is a newb question. If I choose to buy two hard drives for a new iMac, when I receive the computer in the mail, will the operating system be install on the SSD or the regular hard drive? I ask this because I read that putting the operating system on the SDD is better, but I do not know how to move it over if it naturally comes installed on the regular hard drive instead. ***also instead of making a new thread about this, quick question: will a top of the line new iMac be able to play starcraft 2 on the best graphics settings without lagging? I currently have a 2009 macbook pro which is still occasionally skippy on medium graphics even if I switch to high performance mode. Thanks!
