Been thinking about getting another 8800GT so that I can add a third of fourth monitor to my Pro, but it seems it's not available on the Apple site anymore. I can't find it ANYWHERE online either. (Don't live in the US, btw) Now the only things available are the 4870, which apparently can't run alongside the 8800, and which you can't put two of into the Pro, so that doesn't help, and a new one by NVIDIA, GT130 I think, but that's for for Mac Pro 2009 models only? How am I supposed to upgrade now? So much for the much touted upgradability of the Mac Pro... Anyone have a suggestion?
