I just tried it and Dalaran runs smooth now. WoW in general is stutter free and a nicer experience. I have been running WoW on my core i7 and it was in the back of my mind that performance wasnt as it should be on a top spec system.

Well its Win 7's cpu core parking causing the issue. Vista and XP are NOT affected.

I don't play wow anymore, so can't try those, but when i did play i got terrible fps initially with my i7 (well, not terrible, but terrible considering it's an i7 ), so i found the following

those that are having performance problems with quad cores, by default it only uses cores 1+2, for me that meant it used core 1 and HT on core 1, resulting in terrible fps. Once i changed affinity to Core 0+2+4 (actual cores, not HT threads) my fps increased a lot.

As for the OP, try changing core affinity to Core 1+2+3 (leave core 0 for windows etc as wow only uses 3 cores iirc), overclocking your CPU will help a lot too.

Edit - Open "Wowfolder\WTF\config.wtf" change (SET processAffinityMask "xx") the xx will be 3 i think by default, which is core 0+core 1

to use cores 1+2+3 change it to 14, to use all 4 cores change it to 15.

Core Mask #
0______1
1______2
2______4
3______8
4______16
5______32
6______64
7______128

To use certain cores, just add together which ever numbers are next to the cores you want to use and put it where xx is above, save then when you start WoW it will automatically use those cores. (i.e. if you have an i7 and want to use cores(not HT cores) 2+3+4, which is core 2+4+6 it will be 84)

Hope that helps

Edit - After that i didn't have any performance issues, and WoW used cores 2, 3+4 (core 2, 4+6 in my diagram thingy above) without problems, checking resource manager it seems only my HT threads are parked, which i didn't use for WoW anyways, so i doubt it would have made a difference.

But using default affinity settings wow will use (or did, when i played anyways) core 0 and HT core 0 (cores 0+1 in diagram thingy), so you should get abit of a performance boost.
