Hey all, my current 2007 iMac is getting slower and slower and it's time to upgrade to one of these brand new iMac. I would love your input on the right config as i want to avoid issues like forking extra $ for an option and not getting the benefit out of it (e.g. more powerful processor that's mismatched w. internal RAM or something like that). My usage is somewhat standard - some gaming, streaming (on Mac or off to the Apple TV), internet, light MS office and some light pic retouching (nothing crazy/ professional). I know a few things already - i want a 27 inch to get the latest processor (and also like the screen size), am leaning towards the SSD (as I like the speed and owns a 1TB external hard drive -> my question is around 256G vs. 512. the SDD would house the OS, so is 256 is big enough?), as for processors and RAM am not sure what to do there. Can you give me some reco? thanks!
