Apple on Monday refreshed its iMac line with faster Intel Core 2 Duo processors and an optional more powerful graphics processor on its high-end 24-inch model.

The new iMac is available in three basic configurations: a 20-inch 2.4-GHz model ($1,199), a 20-inch 2.66-GHz model, and a 24-inch 2.8- GHz model. The 2.4-GHz iMac comes with an ATI Radeon HD 2400 XT (128-MB memory) while the 2.66-GHz and 2.8-GHz models come with an ATI Radeon HD 2600 PRO (256-MB memory).

There’s also a built-to-order 24-inch 3.0-GHz model featuring Nvidia GeForce 8800 GS (512-MB memory) that lists for $2,199 at the Apple Store, with 2 GB of memory and a 500-GB hard drive.

The new Intel Core 2 Duo processors that power the iMacs feature a 1,066-MHz front-side bus and can be configured to support up to 4 GB of 800-MHz DDR2 SDRAM memory.
