Here are the latest Apple rumors from the blogosphere.

“The first OS X 10.8.3 beta includes drivers for AMD’s Radeon HD 7900-series video cards, the 7950 and 7970, notes Netkas.org. The cards aren’t in any current Macs; they’re in fact based on AMD’s new Graphics Core Next architecture, and are each equipped with 3GB of DDR5 RAM. It’s believed that Apple could be including the drivers for the sake of a new Mac Pro.” — “MacNN” (www.macnn.com)
