I have a 2010 MacPro 5,1 with an original vid card and I am going to upgrade my display to something 4k. I understand I will need a new video card to support the higher resolution and after googling around about it, I am entirely overwhelmed, I have absolutely on idea which cards would one the right ones for me. Anyone have any suggestions about that? I'm not afraid to flash one, if that opens up options. I would definitely like to get a card that doesn't require special drivers if possible, in other words once its flashed will work with updates from Apple. Is that even possible? Metal will be important for the future. Otherwise I don't play games or anything...just run my DAW (LPX) and other music apps on it mainly....which means a "quieter" card is more interesting to me than some kind of super fast GPU, but what have some of you done for this? For the display, I'm presuming that I want to get one with DisplayPort inputs on it? Anything else to keep in mind? Thanks in advance.
