Totally, I guess I was looking at it through my eyes and my requirements.
I guess like everything, it's how much you are prepared to spend and how long you have to wait around for rendering. In short, it's the editing experience which is key... if you can edit smoothly, you are good to go. You can always make use of proxies if you need to help your computer out... and then drop in the full res files at render time and leave it over night.
