Hi folks, I've decided to wait for the new Mac Pros and try to squeeze a bit more life out of my G5 "Cypher" (dual 2.0, PCI-Express x16 bus, late 2005 with 8gb/2tb). I'm a video editor, just starting to work with HD (boy, that AVCHD to AIC conversion is a killer!). I'm hoping that with a new video card (I have the original GeForce 6600LE) will improve my rendering and display speed. First question: Given the antiquity of my processor, will a new graphics card greatly improve my HD video rendering and display speed in FCP? Second question: What non-extravagant options are available/advisable for my PCI-E x16 bus G5 system? Most of what I find through Google searching is either no longer supported, no longer carried, or available through iffy-sounding suppliers. Thanks to any advice; I welcome your questions and abuse.
