So I am planning on buying my first Mac. I have asked everyone for Apple gift cards for Christmas. I have a couple of questions I guess. I have decided to get the 24" iMac, because I cant upgrade the screen at a later time. I am not sure whether to get the 2.4Ghz or 2.8Ghz. Is the 2.8Ghz worth the extra $250? Also I was thinking on getting a 1TB HDD. Is this an overkill? I am using this computer for music, video, email, etc. I am not a gamer, and I dont edit video either. I was going to keep the standard RAM and upgrade it myself to 4GB since that is cheaper, than ordering it with 4GB. I'm exicted for to get my first Mac. Any advice before ordering? Thanks!!!
