For windows it seems to depend a lot on the OS and drivers what will make for the best option when it comes to your question about the videocards. I am not sure how well Mac's handle multiple videocards. If adding one extra cards simply doubles your total framerate go for that because you'll be much better of financially. I am sure you can find more on this on the internet.
Thanks. It's really difficult to get answers that are relevant to not only multiboxing, but boxing on a Mac. Most discussion about performance revolves around just playing one game at a time, which is silly for me because there's no such thing as a game that could bring my computer to its knees if I were only running one instance of it.
