WoW FPS

I recently built my computer. It's a beast. I haven't touched the speeds or voltage yet cause I don't really need to. My comp is overkill for what I do. I play wow. I have:

i7 930 @ 2.93 (dunno why its this but thats what I'm getting from cpuid)
p6x58d premium mb
XFX ATI 5850 XXX edition
OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (although its clocked at stock speeds right now (1100) I'm nervous to change em)
Corsair 750w psu
etc.
etc.

I've been playing a couple weeks now on my comp and I don't experience lag or anything and I'm using ultra settings. However, when I enter org I am getting 45 fps when looking at the epicenter of org. when I look away it goes back to 60.
My question is, with what I have should I expect to get 60 FPS ALL the time on maximum settings in wow?


Side note: When I disabled the vertical sync, my FPS shot up to 200 in some areas but still back down in org. Any input on this?
