I currently have the ati 1900xt 512mb which works well, but is it going to be fully compatible with snow leopard? What are my other options? I'm not a freak about top performance but I want a good card. I do use video editing on the Pro. I wanted to look into the nvidia 8800 model for my mac, but where do I find it? It's gone on the apple website. What other good options are out there? Many thanks for your response!!
