IMAC 21.5 INCH INTEL CI5 2.5GHZ 4GB MEMORY 500GB HARD DRIVE ATI 6750M

The new iMac features next-generation quad-core processors and the fastest graphics ever in an all-in-one computer. It also brings Thunderbolt I/O technology to the desktop for lightning-fast data transfer. And a new FaceTime HD camera lets you make full-screen HD video calls. All from a beautiful widescreen LED-backlit display that takes up just a sliver of your desk. It's everything you want in a desktop. Now more powerful, more advanced, and even more incredible than before.

New Intel Core i5 and i7 processors.

• New quad-core Intel Core i5 processors are standard on the new iMac. Choose a 21.5-inch iMac with a 2.5GHz or 2.7GHz quad-core Intel Core i5. Or expand your view with a 27-inch iMac featuring a 2.7GHz or 3.1GHz quad-core Intel Core i5. You can even configure iMac with the fastest quad-core processor available - the Intel Core i7. All models use Intel's recently refined chipsets. That means the new iMac performs nearly twice as fast as the previous generation, adding a new dimension of speed to everything you do. And since Mac OS X is designed to take advantage of each core, it captures every last bit of performance from the processor.

Advanced AMD Radeon HD graphics.

• When you need performance for things like playing 3D games, editing HD video, or running design software, the discrete AMD Radeon HD graphics in iMac go to work. You see more frames per second and experience better responsiveness. With the AMD Radeon HD 6970M, the top-of-the-line 27-inch iMac offers the best graphics of any all-in-one. But no matter which iMac you choose, you're guaranteed superior graphics performance. With up to 2GB of dedicated GDDR5 video memory, these processors provide up to 3x faster performance than the previous generation.

Thunderbolt.

• Thunderbolt technology has arrived - and Apple computers are the first to have it. With one tiny port, you get lightning-fast transfer speeds and huge expansion capabilities. Two 10-Gbps data channels per port mean you can transfer data up to 12 times faster than with FireWire 800. And donÕt worry about a single drive or peripheral tying up the Thunderbolt port: You can daisy-chain as many as six devices plus a display. The 27-inch iMac includes a second Thunderbolt port for even more expansion possibilities. Connect up to six more devices or a display or two.

Apple iMac screens typically display 16.7 million colors, good enough to get close to 100 percent of the sRGB color space. But, if you are a photographer or a graphic arts professional, working with an Adobe RGB gamut is essential - so that the color values that you see on the screen as well as visible highlight and shadow details reflect the actual colors in the image file.

So, how can you view Adobe RGB color on an affordable and powerful all-in-one Apple computer? By using the mini DisplayPort on the current iMacs (including iMacs dating back to 2009), you can add a second color accurate display and do your precision work on the second display. And, if you start with a 21.5 inch iMac and add a color accurate display, you can get a larger workspace than is available on a stand-alone 27 inch iMac at a lower total cost.

The following are some of the color accurate displays (listed from least to most expensive), a display calibrator and adapters that would be used to connect your second display.
