Mavericks consumes a lot of ram ,ironically.
As a rMBP 13" owner, 8GB is enough for normal usage but if you want to go into video editing and opening a lot of applications at once, go for 16GB. Mavericks consumes a lot of ram ,ironically. I get page outs when I have more than 10 tabs opened and that is just with Safari active only.
agreed. i'm fine if with it except when it starts paging out.. that's a nonoMavericks simply manages the RAM differently and does a lot of "caching" and "preloads" apps you use regularly. (Windows Vista/7/8 works the same way by the way)
And in my opinion, that's how it should be. Unused RAM is wasted RAM.
