Antixmother,
One thing I noticed during my years of playing WoW is that every time a new patch comes out, it is usually one of the addons installed that craps on the FPS. For me, for the longest time, it was always Recount. I would have to disable recount until an update for it came out. I know you said you've updated your addons, but were all of them updated for 5.1? A new patch would net me less than 30fps just standing around in SW. Disabling it brought it back to normal. Disable all addons and start enabling 2 or 3 at a time until you reach the culprit.
