Can some of you out there with this setup comment on the impact this video card has had on your system? After doing some research, I'm planning on purchasing this card in the next few days. I've seen some comments on driver problems, but I wanted to see if that's how everyone feels or just the few I found googling around. I'm not ready to buy a new mac pro yet, so I'm wanting this card for video production and 3D work. Any feedback would be appreciated. current setup Mac Pro 4,1 2 x 2.26 quad core intel xeon 16 GB memory Radeon 4870 512MB thanks! main apps include maya, cinema 4d, all of adobe, and fcp.
