Hi all, first le me say this is a fantastic forum with lots of great contributions from its members! Well done! As the title says, I am a potential switcher looking to purchase my very first iMac. As I know virtually nothing at all about Macs here I am with a request for your guidance in choosing the right specs so as to make sure I spend my money wisely. I've ruled out the 27" as it's too big for my workspace. I use my computers for Internet, email, MS Office and some occasional desktop publishing (Quarxpress and InDesign). I am not a gamer, though I might be tempted to put the iMac through its paces, but I would probably go for car racing or flight sim at the most. What I would also like to do is record music (perhaps using Garage Band at first). I would also like to install Windows on my iMac. I understand this can be done quite easily. Do you think a 21.5" iMac with the following specs would suit my needs? Intel Core i5 quad-core 2.9GHz 8GB SDRAM DDR3 1600MHz - 2 x 4GB 1 TB Fusion Drive NVIDIA GeForce GT 650M 512MB GDDR5 My questions are: 1) Would I need the faster processor (Intel Core i7 quad-core 3.1GHz)? Would I notice the difference? 2) Do I need an extra 8GB of RAM? 3) I understand Fusion Drive is the way to go. Would I benefit from it considering my requirements? Will the Fusion Drive give me any problems if I also install Windows? Thank you for any advice you can give me!
