I was reading a white paper from Silverado about FCP X and MacPro requirements. They are clear in their paper that they would like the reader to upgrade to the highest spec machine they make. But my MP is a 2008, 2.8ghz model and I'd like to know what people here think are the worthwhile improvements I can make to this machine to make FCP X work a lot faster...without my replacing it with a more recent MP. I'd love FCP X to make better use of my machine. Currently it has 16GB of memory and an ATI 3870 gfx card. Would I see a nice performance boost by increasing the RAM (I have 8 x 2GB) and swapping out the 3870 for a 6xxx series? My FCP 7 use is average. Not a power user.
