27-inch 3.1 GHz Apple iMac

1. PCMag.com

The 27-inch iMac earns a 4 (out of 5) star rating from PCMag.com. Joel Santo Domingo calls the PC "as powerful as an Asgardian thunder god," but fails to give the all-in-one an Editors' Choice award. "For the rest of us who don't live and die by deliverable deadlines, however, other recent all-in-one PCs out-innovate the Aluminum beast," he writes.

CNET gives an Editors' Choice award to the 27-inch Apple iMac. Rich Brown says the iMac has better overall performance than any other all-in-one on the market, and gaming performance is impressive as well. However, he wishes the system included an HDMI port.

3. Computer Shopper

It is yet another Editors' Choice award for the 27-inch iMac, this time from ComputerShopper.com. Jonathan Rougeot raves about the sleek design, gorgeous display and overall performance. "The iMac's performance here is high enough that all modern games should be playable, provided you're willing to occasionally drop down the resolution a bit and switch off a few graphical settings," he writes. Like most reviewers, he wishes it had a Blu-ray drive and HDMI port.

AnandTech.com delivers far and away the most comprehensive review of the 27-inch iMac, comprised of page after page of benchmark tests and hands-on impressions. "I like LG's 27-inch panel that Apple uses, I like Sandy Bridge and thus I like the 2011 iMac. If I lived a different life it'd probably be my desktop of choice, and that's something I never thought I'd say," Anand Lal Shimpi writes in conclusion.

5. Macworld

Macworld gives the new iMac 4 mice (out of 5). At 1,024–by-768 resolution, all four iterations of the 2011 iMac deliver similar frame rates in "Call of Duty 4," but upping the resolution to 1,920-by-1,080 results in the 3.1 GHz 27-inch iMac far outpacing the other configurations. It delivers 87.8 fps while the other versions achieve very playable, but still diminished, 50 to 60 fps scores. He also reports this year's iMacs are much speedier overall than last year's model, which contained a first-generation Intel Core processor.
