Apple has updated its iMac range with the addition of Intel Core 2 Duo processors and NVIDIA GeForce 8800 GS graphics cards – although the latter is an additional option.

The updated desktops boast, as standard, a 1066 MHz front-side bus and up to 4GB of 800 MHz DDR2 SDRAM memory, along with established features including AirPort Extreme WiFi networking and Bluetooth and Ethernet adaptors.

Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing announced the new models saying, “With the latest Intel processors, a faster new graphics option and more memory, customers now have even more reasons to love the iMac.”

Full details of the three updated models' specs are available online at the Apple store, as is the pricing and optional extras information.
