^ peak gaming hours for most online games are like 7pm-2am
A Q6600 will probably need to be clocked above 3.0GHz to run WoW smoothly, as WoW only really uses 2 cores to maximum potential I believe. Cataclysm will be more demanding than WotLK as well so I am not sure if a fast clocked Q6600 will be enough to run everything at max settings @ 1080p, but I can't say for sure. It will defo be able to run with fairly high settings though.
High fps in cities is not really all that important anyway, more important are your fps in instanced dungeons / raids or battlegrounds / arenas.
Ideally to run WoW: Cata at the highest settings smoothly @ 1080p, you will probably want to have an i3/5/7 overclocked to at least 3.5GHz, and a GTX 460 1024MB equivalent or better.
(May be a bit of overkill, but these components really are not all that expensive and offer very good price : performance for a gaming setup)
Addons will affect fps if you have demanding ones or a tonne of them, but a few simple ones shouldn't present too much of a problem.
I will let you know what my fps is like when the game comes out with an i3 & 460.
