I know you can't compare retail and private server, but from this page:
Spell damage coefficient - WoWWiki - Your guide to the World of Warcraft
you can actually calculate what your damage would be on retail. At least to get a picture.
According to my calculations and If we presume everything worked ok, you should be able to pull off 2600 SB non-crit. And I don't even count talents in ^^
