Hi! I was hoping that you guys could help me decide on a few things before I purchase an iMac! I have decided on getting the 27" iMac but I don't know if I should do a custom build. I do graphic design work, so it'd be nice to open Illustrator/InDesign/PhotoShop at once while surfing the internet. (That scenario wouldn't happen a lot but it'd be nice to have that option.) I don't plan on buying more RAM since I've been told that's something I can do later. I also would like suggestions for an optical drive that can play blu ray movies (commercial, not ripped stuff) but that can also be used to play cd's and dvd's...basically turning my iMac into a TV when needed. I also want the drive to write dvd's and cd...blu ray would be optional. It'd be cool for it to be USB 3.0, but I'm not sure if it's worth it. I'd value your opinions on this! I also have waited because I want it to come with Mavericks pre-installed. I have read it varies in other forums. I'd like opinions from people in the US, since that's where I am. Should I get the 3.2GHz quad-core Intel Core i5 or 3.4GHz quad-core Intel Core i5? Why? Assuming I go with the latter, should I upgrade that to 3.5GHz Quad-core Intel Core i7? Why? For storage, what would you recommend and why? For graphics, what would you recommend and why? Sorry for all of the questions, but I plan on having this computer for a while and it's expensive, so I'd like to make the best decision, in terms of my use. Thank you for reading this (sorry it's so long) and for your opinions.
