I'm looking for some help in purchasing a 27" iMac, mainly for my wife who is a part-time wedding photographer. It's primary use will be editing 30MB RAW files in LightRoom 5. We are on a budget and looking to spend as little as possible, but willing to pay if it means the machine will last longer. Hoping to get 5 years out of it. We get an education discount as she works at a university. Fusion drive is a must. Will be able to buy in 1-2 months. Option 1: 2013 27" iMac 3.2 i5, 1GB 775M w/ 1TB Fusion Drive ($1929) Option 2: Refurb Late 2012 27" iMac 2.9GHz i5, 512MB 660M w/ 1TB Fusion Drive ($1669) Option 3: Wait for the new 2013s to end up in the refurb store Option 4: Wait for 2014 iMacs (yeah, right) I'd appreciate any advice. I like to have the latest and greatest Apple stuff but don't know if ac wifi, PCI SSD interface, and Haswell is worth the money. Time isn't a huge issue as we're at the end of wedding season so editing won't get busy again until next spring. Also, anything will be better than the 2009 13" MacBook Pro she's editing on now. Thanks for the help!
