I know this has probably been answered a billion times, but I need the answer for my specific needs. My daily use will be: Web browsing iTunes Watching HD Movies Bit Torrent HandBrake Dvd Burning Windows Parallels Social Networking iPhoto and thats basicially it. Can someone tell me if I really need the Core i5 2.8ghz, or should choose the Core i3 3.2ghz. Mind you, I dont wanna max out the machine with daily use...but dont want to overkill it. Thanks.
