I have found PC Mag be fairly reserved in their reviews over the years. I thought it was interesting, and a good sign, therefore to see them rate the new iMac at a 4.5 (4 is pretty good for them) and give it an editor's choice rating. http://www.pcmag.com/article2/0,1895,1912969,00.asp "Other programs, such as the QuickTime player, show a marked improvement. Before Core Duo you really needed a PowerMac G5 dual or Quad tower to view 1080p high-definition movie trailers without the annoying audio or video stutters seen on the original iMac G5. On the new iMac, 1080p QuickTime 7 HD videos play smoothly without a hiccup. The Superman Returns and King Kong movie trailers look phenomenal on the new iMac." Here's their brief benchmark comparison: http://www.pcmag.com/image_popup/0,1871,s=1564&iid=124874,00.asp There's a link re their methodology at the end of the review.
