Do you get extra gold for doing quests at lvl 80

I was wondering if it was worth it for me to level up my guy to lvl 80 through dungeons and then start leveling in northrend zones for extra gold but im not sure if you do get extra gold for doing these quests at lvl 80.

Yes, you get extra gold (replacing experience) for all quests once you hit 80. It can be lucractive to do all quests in Outland/Northrend at that point, especially if you hate doing the usual dailies.

Thanks a lot man!
