Before I jump up and try buying one of these, I want to ask if anyone has ever installed an NVIDIA Tesla on a MacPro? If so, does it work under OSX properly? I did a bit of googling, but didn't quite find the answer to what I was looking for. I hear that with a MacPro 1,1, you have to be careful with how much power you are using to avoid overloading your PSU. Why do I want this? I want to get into some hard core CUDE/OpenCL computing. If I can't do this on my MacPro model, then I'll have to resort to using my other PC. Any ideas? Thanks. Shogun.
