Well, the new iMacs are here and I'm really looking at the prior gen refurb 27" i5 model. I'm currently running the last white iMac. C2D 2.16Ghz with 3gb RAM and I believe X1600 video card. Maxed out 250gb HD. I have plenty of external storage but iTunes and iPhoto get flaky when libs are stored on my Drobo. I do no gaming at all, heavy Handbrake, iPhoto, iMovie, iDVD usage. Working my way into Final Cut. Also do minor image editing in Pixelmator and web/PHP development but that is no big deal. Should I pull some money and spend the $1600 on the i5 iMac? Or should I live with my C2D 20" for another year? Will the jump in performance for video encoding and photo editing be noticeable?
