I am currently using a Radeon x1900 512MB card. It seems to work well for video editing, and I've enjoyed it. But I am really wanting to get into gaming on Windows with Boot Camp (flying and racing simulations), and although I have a lack of knowledge with video cards, I believe I can do better with what I have right now. I know that the nVIDIA 8800GT is available. I just have a few questions about possible configurations. Please answer them all if possible. Does gaming work well with the 8800GT on Windows even if there is no official driver for it on Windows? (this is what I have read) Would I see a decrease in performance with things like video editing, etc, if I got the 8800? Does it work well with video editing? The mac pro has more than one slot for video cards. I am not against using more than one if possible! What do you recommend? Is it possible to use 2 8800's in the machine? Would both PC games and the Mac recognize a total of 1GB to handle gaming and video editing better? Is the Radeon 3870 a better fit than the 8800? What's the best solution in your opinion with my needs and requirements? I do appreciate your time and feedback! Thank you.
