I have a Mac Pro 2009 with a 3.33 Hex and 24GB ram. It has an older ATI 4870. I am wondering if I upgrade to the newer ATI 5870, would I see much of an improvement in FCPX or After Effects? I know games will see a pretty good boost in FPS, but I really don't game that much. Thanks for any help. I tried searching this topic already and couldn't find any info on it.
