Hey, Since I got quite a bit into game developing and stuff again, I thought my Mac Pro could use a graphics card upgrade. I plan on running Maya, ZBrush and probably the new Unreal Engine once it gets a little bit more polished. Photoshop also gets some use of course. I currently have a Radeon HD 5770 (the Mac one) installed. I don't know alot about CUDA. OpenGL and all that stuff, so a little light in the dark would be nice As far as I got it, Maya performs better using CUDA graphics cards. Is that right? A few possible cards I read into: The Quadro 4000 Radeon HD 5870 GTX 285 Mac Edition Radeon HD 7950 Mac Edition As you can see, I'd like to get something that kind of works for the mac out of the box. So firmware-flashing windows cards are kind of a no go. Except it really is the SO much better choice About the Quadro 4000 I read kind of mixed opinions. Alot of people say they gained a hige performance boost, others say they barely feel a difference to the 5870 for example. The 2 main options for me would be the 5870 and the Quadro I guess, but as I said I don't have a clue about graphics cards If I would go for the Quadro, I could use both the Quadro and the 5770 if I got that right (since they both use only 1 power connector). Is it possible to tell Maya to only use one of the 2 GPU's or so? I'm really quite tapping in the dark here and would be happy about some opinions. btw: I don't plan to game with it.
