If you meander on down to the Apple store this morning, you'll spot some nice little spec bumps to the MacBook Pro range -- without any increase to the prices. For a start, you can now splash out on a faster AMD Radeon HD 6770M discrete GPU with your 15-inch or 17-inch lappie. Even better, there are some CPU improvements to be had: the 13-incher gets the option of a 2.8GHz Core i7 or a 2.4GHz Core i5 dual-core processor, instead of the previous entry-level 2.3GHz i5 (and it also gets its HDD notched up to a minimum 500GB, or max 750GB). The 15-incher now goes up to a quad-core 2.4GHz i7 -- the same speedy processor that comes in the updated 17-inch variant. Oh, the cost/benefit dilemmas.
