I'm going to dig for awhile to find it, but some time ago I noted that the AGPM kext had entries for GT120 and GTX260. I postulated that a Mac GTX260 must have been in the works in past, but it never came to fruition. So FedEx shows up with a box from NorCal the other day and GUESS what was inside it? The OEM Apple GTX260 !!! Complete with MiniDisplayPort and Apple PArt Numbers !!! The ROM is unique and offers some fixes to issues on cards we couldn't flash well before. It is somewhat buggy in that MDP doesn't work unless connected at boot, ie, no hot plug detect. We all wondered why it took so long for Nvidia GTX285 to show up. While we did miss out on MDP, the Dual DVI GTX285 is quite a bit faster. Would love to know the full story but my friend from up North is being quite SILENT on details.
