Hello, I'm using a Mac Pro 5.1 with ML 10.8.5.I'm looking for a solution to run 3-4 Gtx titans externally.I lean towards a Cubix Xpander with MacVidCards. My main concern is,does it work at all. i would use it mainly for Octane Renderer with C4D. it would be nice if any pros could give me some information about this. i have read a couple of threads here where Mavericks has some issues with Cubix-titans combination. I don't really have to switch to a PC,do i?
