So, i'm shopping for a new iMac. I found this a refurbished 2011 iMac with a 21.5-inch screen, 2.7GHz Quad-Core Intel Core i5, 4GB memory, and a 1TB hard drive for $1,249.00. I get a student discount at Apple but, the refurb is a really great deal. I was wondering if I could get some opinions on the new, rumored features vs. the cheap 2011 model. I don't want to spend more than $1300 if possible (I'm a senior in high school so i'm not made of money). I've read all about the new Ivy Bridge processors and the other rumored features.I need it to be able to handle heavy 3D work in photoshop and I do a lot of Premier Pro video editing so, a good processor is necessary. I mostly care about the cost for what you get. Because of the back to school bonus they do every year, I figured I could sell whatever it is to help with the computer's cost. Thanks in advance for any help!
