Hello, I've been using a PC all my life and I'm going to be switching to an iMac fairly soon. First of all, I'd like to thank all you guys for all the countless helpful posts as you don't get the recognition from all the lurkers that you deserve. I'm very unknowledgeable (is that even a word?) when it comes to computer mechanics so I really need your help! I use my computer for: Email, web surfing, downloading a LOT of crap, IM, music, movies and I use it for school work. I would like to play the occasional game like GTA IV and Halo. My main uses are downloading and watching movies on it, but I enjoy doing most things on my computer. I don't use hardcore video editing software or intense graphic stuff, but I do convert video format for iPod etc. I have enough money to get the top of the line, top specs best iMac, but I don't know if it would be worth it if I never max out the processor or graphics card. I will also be getting to 4 GB RAM from crucial. I'm hoping the computer will last a couple years, so should I max out so it will cope well with future software? Should I upgrade the internal hardrive of the iMac or just get an external? Also, why do people recommend getting the Time Capsule so much, do iMac wipe themselves often? Thank you so much for reading and I hope you can help me out as much as I've seen you help others!!
