Hi there, hopefully you could help me - I'm working a lot with After Effects CS5 and Premiere CS5 and I hate this because of the ATI HD 5870 in my MacPro. So I plan to upgrade and need to know, if my configuration will work. My System: MacPro 5,1 2 x2.4 Ghz Quad-Core Xeon 12 GB DDR3 New Cinema Display I want to buy an EVGA GeForce GTX 570 HD http://tinyurl.com/6eupzgz So I have four questions: 1) Will it work under Lion as second Card only for rendering stuff? 2) Will it fully work under Windows 7 in Bootcamp? 3) What kind of Display-Adapter is necessary to connect it to my Cinema Display? 4) What kind of Drivers are necessary under Lion? Pleaser help guys thx!
