Right now I am doing a lot of work in Maya and AE. I have a 5870 in my MP and it works pretty well. I was doing some dynamics stuff in Maya, specifically some simple ncloth stuff, and it was pretty dang slow. I opened up the same scene on a Dell workstation with a fairly old, at least I think fairly old, NVIDIA Quadro 3800. There was a huge and noticeable difference. I have looked into some of the quadro cards for Mac, but everyone says the drivers are awful and its really not worth it. And is sounds like that isn'st as much of Apple's problem as it is NVIDIA, and that NVIDIA just has better drivers for PC. So I guess my question is, would it be better for me to get a PC Quadro card and just use it for bootcamp? Also, how much of a difference would there be between the 5870 and say a quadro 5000? And considering the whole quadro line up, at which point in that line up would I start to see better performance than the 5870 inside of Maya's viewport? Or would every quadro card, even the very cheap quadro 600, provide for better performance in Maya? Also, would it be better to go for AMD's professional GPUs or NVIDIA's? Now I am pretty far away from buying a whole new system, but the idea has come up of selling my current MP setup and building my own PC just for this. Of course if it comes to that, I would much rather just put in a PC card just for bootcamp since I absolutely love OS X. Either way, I will keep my MBP and whatever laptops I get down the road will for sure be Mac.
