How much gold do you "need" to get the "best" gear?

[XghostzX]

Heyo,

I recently reached end game.

Wanted to get an estimate of how much gold I should obtain in order to get the "best possible gear". I know I've missed some mythics, or whatever they are called (sorry, I'm an AL newbie). But I'd love to get a goal of how much gold I should get before buying anything.

I know a new cap is coming, so I'll save up for it. I've currently farmed up about 400k, so I know there's a long way to go.

Any tips/estimates would be greatly appreciated!
