I'm not even sure if I'm posting in the right section so please excuse me.
I have a MacPro5,1 (Mid 2010)
I'm trying to add a nVidia Quadro 4000 in addition to the factory default ATI Radeon HD 5770. The aim is to upgrade my graphics and have additional displays but I'd like to know if this will work. I have 2 monitors right now and I'm hoping to add 2 more (4 total) with this scenario.
