It's good to know that we have friends in San Jose. Latest Beta Yosemite Web Drivers have GTX980 support !!! You can literally order one from Newegg and use it. We will be offering versions with better support when we have time to work on them. With any luck we will have EFi figured out, at very least PCIE 2.0. For now avoid GTX 970, as it isn't in the drivers yet. It seems there is no OpenCl yet, and I have not been able to get any indication of CUDA yet as CUDA-Z doesn't function in Yosemite. (unless you use new 64bit Beta) A short family visit has turned into a very different experience and I have had to rely on my partner back in LA to do testing. Will do more thorough report when I am able to return to LA. EDIT : 970 DOES WORK !!!
