What should my dps be a fresh lvl 80 world of warcraft?

Unholy isn't as viable as dual wield (both slow weapons) frost, or even blood for that matter. If you were to go blood you would stack strength and blow the crap out of everything in your path. Frost has major AoE's as well as some awesome single target nuke, haste is good for frost as well. 1.4k-1.9k is decent.
