  • Anyone who bought last year's redesigned iMac doesn't need to upgrade, but for owners of older models or anyone looking to switch, the latest 27-inch Apple iMac offers a wide-ranging set of internal upgrades.


  • Though it's mainly a speed bump, the inclusion of the latest 4th-generation Intel Core i5 quad-core processor and Nvidia GeForce GTX 775M Kepler graphics bump the Apple iMac 27-inch (Intel Core i5-4670) back to the top spot on our high-end all-in-one desktop list.

    You'll buy the iMac for its beautiful display and robust performance, not the thickness of the bezel.


  • Lenovo continues to make strides in the slim desktop PC category with the IdeaCentre H520s. It combines a slim space-saving design with ease of use and a range of entertainment features. It features an Intel Core i5 CPU, 6GB of RAM, built-in wireless connectivity and a 1TB hard drive. The slim design does limit future expansion, but it comes with everything most users will need.


  • is a high-tier desktop suitable for power-seeking users who don't want to pay too much for their computer. Graphics performance is subpar so gamers would do better with another desktop, but other power users would definitely enjoy this Lenovo.


  • Beautifully engineered, the Alienware X51 is a quick, small, and surprisingly affordable gaming PC. No competitor can match its killer combo of pint-sized chassis and powerful performance.


  • For those who can afford it as we tested it, the Alienware X51 R2 delivers a premium gaming experience in a compact design that's both stylish and well-suited for the living room. You can also of course configure a less expensive build-out on the Dell Alienware site. Job well done, team AW.


  • Vizio's top-of-the-line 27-inch touch all-in-one gets a modest update but stays traditional compared with detachable, convertible alternatives.


  • With its great feature set and lots of performance, the Vizio 27-inch All-in-One Touch PC (CA27T-B1) is a system that can deliver on the promises made by its futuristic design.


  • Vizio's latest all-in-one looks good and performs well, but Vizio needs to up its peripherals game.


  • The Acer Predator AG3-605-UR20 is a solid choice for anyone shopping for an off-the-shelf gaming desktop.


  • Acer has finally delivered a gaming desktop with an advantage over the market's veterans. While a sense of awe or occasion might be missing from this bare-bones rig, it's hard to argue with a legitimately capable gaming desktop that is sold for less than $1,500 and offers respectable upgradability. Acer's Predator G3 offers outstanding bang-for-the-buck. Gamers on a budget should absolutely consider the G3.
