Hi everyone. I just bought an iMac 27", 3.1 GHz i5 Quad-Core (the new high end model). However I was wondering if I should take it back now and get an i7 at 3.4 GHz? I just saw the geek-bench score for the i7 and was wondering if it is worth taking it back and paying another 240$ AUD for the i7. I think the i7 is considerably faster but seeing as I am only a student and do not really need the extra power do you think I should bother? It would really only 'future-proof' my machine. And also are you planing on buying a new iMac? Or are you going to wait for the next generation? Thank-you!
