For the record, this is still happening, six months later. It's particularly bad on review pages. I've an idea where the problem stems from, it seems to be connected to all the external sites Gamespot links to. I tested this by using an adblocker to block all the Facebook, Twitter and other social networking buttons, with each one I block the problem diminishes, so that now it only pauses for about 5 seconds every time a page loads. If I could track down the last components the page is loading I could probably eliminate the issue altogther, but clearly this is still troublesome.
And before you raise an eyebrow, I do have "allow some non-intrusive advertising" enabled so the normal banner ads still appear. I'm not adversed to those, as long as they don't get in the way or affect page loading times.
You can pretty much see it in action, the page loads and then about 10 seconds later the social buttons finally appear, which is what tipped me off in the first place. Best guess is that whatever I've missed is loading further down the page where I can't see it. In the meantime the browser freezes completely and you either have to wait, or deal with IE9 trying to recover the page (which just starts the problem again).
I guess if this was last reported in Sept 2012 and yet still hasn't been fixed, Gamespot's tech guys either think it's solved or could do with looking a bit more closely! Either way it's a bit of a shame as I visit this site pretty frequently.
Lots of people still use IE9, including me, simply because it starts instantly on W7 rather than the 2-3 second delay that Firefox and Chrome always have before loading. The default "switch to Firefox" jibe that inevitably follows (I do also use Firefox, but not as my primary browser) is fine for some, but not for me!
