Hi, we have the latest MacPro with MC 5.5 on Mountain Lion, and ATI 5870. We want to install Davinci Resolve. For this we are thinking about two video cards, GT 120 for basic work, monitor and MC, and GTX 570 for GPU acceleration for Davinci. Will this config work with MC 5.5? Important is that these cards are from macvidcards, and GTX 570 is modified
