This chrominium bug report you linked to a few pages back describes this very behavior. Here:
https://code.google.com/p/chromium/issu ... ?id=422000
Canary indicates that google is working on this, but the results are inconsistent. At best, it matches or exceeds IE's performance. At times, it seems to regress back to the profile of the current stable. It'll be interesting to see what state it's in when v40 goes beta.
Firefox is just an awful mess in general, but project silk indicates they are aware of this and are trying to correct it.

Your cpu may be old, but it's powerful. If it was me I'd try stock clocks and see if the behavior changes. Your gpu is pretty good period...have you updated your graphics drivers lately? Do you notice halting when playing normal PC games?

Wow, now those are some spec's <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile"> But your results...that's very strange. I've never had canary perform worse than chrome stable. And IE has always been rock solid. How does firefox do? Generally, it seems to be the worst of the lot.
Chrome/Firefox reminds me of this joke:
"Did you hear about the statistician who had his head in an oven and his feet in a bucket of ice? When asked how he felt, he replied, "On the average I feel just fine."
