what kind of FPS do u guys expect i should be getting running around by myself, in a city, and in raids?

Depends on the graphics settings, of course.

My PC (Opteron 165 @ 2.7 GHz, GeForce 7600GS) runs WoW at 30 fps on average, 1280x720, 4xAA, all graphics options maxed in the game.

what kind of environment is that in?

In Undercity and nearby locations, mostly.
