It's true what the other said, but however it all comes down on what fight and how you execute the fight.
There are although simulations, that can give you a brief overview on how top tier players DPS will and would look like without misstakes. You can see them here: DPS Rankings in WoW | PvE - Lvl 100 | 6.0.3
As it looks right now, Glad warrior is pretty insane, topping over 20% overall damage, which means they will have the most DPS output of any class right now.
I belive there will be a nerf incomming very soon, atleast before the raids and seasons are released.
