Product Description 

The stunning new all-in-one iMac features a beautiful, completely re-engineered 27-inch widescreen display that's 75 percent less reflective. Third-generation quad-core Intel Core processors and superfast NVIDIA graphics make it the most powerful iMac yet. And it comes standard with 8 GB memory, a 1 TB hard drive, and advanced, high-speed I/O, including two Thunderbolt ports and four USB 3 ports. All in an impossibly thin enclosure that's only 5mm at the edge. 

This version of the 27-inch iMac (model MD095LL/A) features a 2.9 GHz Intel Core i5 quad-core processor as well as an NVIDIA GeForce GT 660M graphics processor with 512 MB of video memory. It also comes with the iLife software suite, which includes the latest versions of iPhoto, iMovie, and GarageBand.
