Hahahaha, holy cow, did the author really write that? So by that logic, if I happen to be on an older single core CPU, and I want to open and edit a very large image, he would still recommend only 2GB of RAM on that computer?
Well to be fair even the largest image files are only 30MB max (RAW) and only 3-4MB if jpeg100.
