I have a Mac Pro version 1,1 which has an Nvidia 7300 GT card (128GB) and I'm looking to upgrade the graphics card as I'm finding rendering AVCHD 1080p to be slower than I would perfer. I also have 9 GB of ram and Two Xeon Duo cores at 2.0ghz each core. Also let me know if you need more computer specs... My eventual goal is to get a RED Scarlet when they are announced but the RED Rocket is too much for my budget and I can always get it later as there are 4 slots in the computer for cards. I'm currently running Adobe CS5 and Snow Leopard right now but eventually I will be on Lion and will likely add FCP X to the mix. Does anyone have recommendations/experiance?
