Hello, I am thinking about upgrading my 6 year old PowerMac G5 dual 1.8 for primarily video editing purposes and using after effects. I got my G5 just before they switched to using intel processors At first I was leaning towards a new Imac i5 2.66 of apple.com but since you really cant upgrade the hd or ram very much, was thinking about purchasing a MacPro off ebay. One in particular is a Apple Mac Pro Intel Quad Core 2.66. Either one would have better performance than what I have now. I'm trying to keep the cost low since purchasing a new mac pro at this point is not going to happen. Any suggestions?
