I used parts of a couple threads to do this, wasn't sure which one to post in, decided to start my own darn thread. Using the "leaked" Nvidia drivers AND Netkas little "ATY_Init" extension, I am staring at desktop rendered by a GTX480. After I read the Hackintosh stuff, I realized that it shuld work in real Mac as well. So, I found a "just fell off a truck" sort of deal on CL for a GTX480, and ran it home. With the same old Netkas ATY_Init that worked for GTX285, I got GTX480 working from OSX desktop on. It behaves differently from Hackintosh reports. Perhaps I need to add Device ID into Netkas extension, or try some of the ones used by Hacky folk. Scores are worse than GTX285 on everything I tried thus far. More pix coming. BTW...CS5 seems to know what it is, and I don't have current CUDA drivers.
