I need some help figuring out which tech specs and processing power I really/truly need for my upcoming 2011 iMac buy. First of all, I would like a 27" model, As I could use a big screen for multitasking. Second, I would like to future-proof it a bit. This is what has me undecided, as I don't know by how much I should improve RAM and Processor in a build-to-order. Would 8GB be a good amount? 12GB?, What about processor? should I try to get a 3.4Ghz core i7? And those extra $100 for 2GB in the 6970M GPU? I don't think I'll be able to afford a SSD. My budget cannot exceed a $2000-$2400 range. I'll be using my Mac for Internet browsing, word-processing, music, movies, plenty of chess software and maybe some light gaming. I'll run CrossOver and Parallels too. Perhaps a BTO for that is a bit of an overkill, but like I said I would like to future proof it a bit, as this buy must last me at least 6-10 years. How will technology change in the upcoming years? Which specs will be most important? Thanks!
