Apple is updating its MacBook Pro line of notebook computers with faster processors and new Nvidia graphics.
The biggest news amid the new MacBook Pro changes is that the 15-inch and 17-inch models now use Intel's Core i5 and i7 processors. The 13-inch model will continue to use Intel's Core 2 Duo processor.
The 15-inch and 17-inch models will also use Apple's graphics switching technology, which allows the computer to automatically toggle between the Nvidia GeForce GT 330M and Intel's HD Graphics processors.
The 13-inch MacBook Pro comes with 4GB memory and Nvidia's GeForce 320M graphics processor. There are two configurations, one with a 2.4GHz processor and 250GB hard drive for $1,199, and the other with a 2.66GHz processor and a 320GB hard drive for $1,499.
The 15-inch MacBook Pro is available in three models: a 2.4GHz Intel Core i5 with the Nvidia GeForce GT 330M and 320GB hard drive for $1,799; a 2.53GHz Intel Core i5 with the Nvidia GeForce GT 330M and 500GB hard drive for $1,999; and one with a 2.66GHz Intel Core i7, Nvidia GeForce GT 330M, and 500GB hard drive at $2,199.
The new 17-inch MacBook Pro features a 2.53 GHz Intel Core i5, Nvidia GeForce GT 330M, and 500GB hard drive for $2,299.
