netkas - just to appease my curiosity, how did you find that ftp site? I have looked repeatedly for links from the evga pages and their is no mac link, just endless references to the CD. Well found! Added in edit: (now I see this is a link posted to the evga forums site that you are told about in the docs)these drivers are noticeably better. I am getting modest improvements in most of the OpenGL scores apart from 2.1. Both my monitors are now working - one off the 285 and one off the 8800. peskaa - worth trying out to see if it solves your problem? Here is a multiGPU CUDA example showing the PC 285 running more than twice the speed of the 8800. (82263 sums per sec vs 35203). My Mac version is supposed to arrive today so we will see what wins. Official Mac vs PC + netkas clever tool.
