So I finally got a capture card (Black Magic Intensity Pro). It works great with FCP but it doesn't work at all for Color. I did some searching and realized that Color 1.5 does not display external video with the GPU that I have (nVidia GeForce 7300 GT) so now I need to upgrade my GPU as well. The problem is that I don't know what my options are and which one I should get that will allow me to work with Color. My MP model is the 2.1, 3.0 ghz, 8-core Xeon. I read that the ATI Radeon X1900XT will work with color but I'm unsure of whether or not my model of MP is compatible with that GPU or if there are other, better, GPUs that are more cost efficient. I don't want to find out that for $50 more I could have gotten a more up to date GPU that works 5x better. So can you help me pick out a GPU?
