I've been negotiating with a CL seller who has a: -3 month old 3.4Ghz i7 with 680mx, 1TB Fusion, 32GB RAM, with 2+ years of Applecare...$2600 is his lowest offer. The config I'm considering buying online is: -3.4 i5, 780m, 3TB Fusion, 8GB RAM...With Applecare & tax=$2700 (Govt discount) I really don't want to wait the 2 weeks to get the mac, and 32GB RAM/i7 would be nice. The positive for a new config is: It's new! slightly upgraded vid card, and 2TB more storage. Is the extra 24GB of RAM & i7 upgrade worth buying used? I do like to play video games on it, but not sure if the extra 24GB would make much of a difference if it's the only thing I'm running. I'm really itching to pull the trigger, so any help would be appreciated.
