Sources for 802.11n cards to install in Core Duo-based Macs Yesterday we noted that MacBidoulle posted (potentially warranty-voiding) instructions for transplanting 802.11n-capable cards from Mac Pros to older Core Duo-based Intel-based Macs.
The benefits of installing this card as an end-user are questionable; your warranty may be technically voided by the installation, and speed increases are not necessarily overwhelming depending on usage.
Still, there may be some side benefits to the new 802.11n hardware, including bug fixes for problems like excessive AirPort process CPU usage.
