No "staingate" at all. Sure, there are many other gates like magsafecrapgate, yosemiteslowgate, unbearablyslowgraphicsgate and such. But no staingate.
Not so long ago I grabbed myself a G4 MDD with 768M of RAM — it was much more responsible in terms of UI. 3-4 browser tabs slowed it down though, while my current rMBP13" from 2012 works ok with a lot more.
