I'm planning on purchasing one of the new iMac's this coming Friday. But I keep waffling on customizaiton options. First off, I'll tell you what I'll be using the machine for: Gaming (World of Warcraft, SimCity, Starcraft II, Diablo III, etc. Don't play FPSs all that often) Video Editing (iMovie, I wouldn't use Final Cut) Audio (GarageBand, etc.) Basic Office apps (Excel, Word, etc.) Internet (of course ) As you can see I don't do any major photo editing, video rendering or major sound recording. So for the machine, I'm planning on getting the 21.5" w/ 16 GB of RAM. My question is two fold: Do I get the Quad-Core i5 or the Quad-Core i7? Do I get the standard 1TB HD or the 1TB Fusion Drive? I'm going to get the 16GB of RAM regardless bu is the processor and Fusion drive really going to be worth the extra $450 in the long run for what I do? I just want to know if I should spend the extra cash on the above features based on what I'll be using the machine for. Any help would be GREATLY appreciated!
