Depends what I'm doing. For editing it's usually just fine. Color and fx work require higher bandwidth. For example, at 2k a single frame is 12 MBytes (times 24 or 25 per second, depending on the project). And we are at the dawn of an era where we are talking about 4k dci or QHD mastering for all. That wpuld be 48 MBytes per frame. So,we're looking at 300 and 1200 MBytes per second for a single workstation. Gigabit is not up to it.
