Your scores are pretty much exactly as they should be. I've concluded that it must be a WoW related issue and googled it a little. First results with "wow raid fps" was this:http://eu.battle.net/wow/en/forum/topic/8381438176
Seems to be a common issue. I can't help you out with that, since I don't own the game, but with that info you should at least be on the right track. You should try finding a solution in the Blizzard forums or just write them directly if you can't find anything helpful.
