Is the flash at the top of the main store page a resource hog for you?

i7 920 OCed to 3.2
Using hyperthreading, one of the Ht core goes to between 40-80%, overall processor usage bounces between 6-16%.
Actually a rather surprisingly large amount for a single banner advert.
The rest of my system with msn steam yahoo 3 browser tabs windows each showing a forum and hotmail open average 0-2% at the low idle clock speed on the processor.
Opening the main page moves the processor to active, where it remains utilising the most of one HT core continuously.
This is rather surprising.

It's not Flash 
.
My MacBook Air isn't a fan though. Loading the page spiked to 50% usage, and each transition was between 20%-50%.
Having said that..... can't say I'd noticed until I opened up Activity monitor and looked.
Can't see why though. Just looks likes a nice bit of Javascript (from the jQuery library), though Javascript isn't exactly my strong point!

Why are you comparing video playback to content display? Nobody else is
I missed the memo that said someone else had to do something before I was able to. Nobody would get very far if someone else always had to do it first. Think about it. In any case, it's not even flash so by your own 'logic', why are you taking about flash at all?
I am comparing them for the painfully obvious reason, that rich content i.e. video, is the primary use of flash on the internet. This was in response to your vapid generalisation that 'flash is bad mmmk'.
You still haven't suggested a better alternative. Anyone can point out the negatives to anything, but without a better current solution, it's just irrelevant whinging I'm afraid.

There is a way to change the interval with which jquery re-calculates the animation tweening, a little tweaking under the hood from say a default 30ms interval - to a less CPU hungry 200ms would increase performance without becoming overly perceptable to the human eye. You could also implement a jquery plugin called "nap" which freezes javascript functionality on a page when a user is idle / focused on another tab/window.
EDIT: Apparently the default animation interval in jquery is currently 13ms - (76fps) so even setting it to 65ms would mean using only 1/5 of the calculations to provide the same animation: at a less potty 15fps.

I posted a thread a fair while back about this very same thing happening to me on the Anandtech website. I use Firefox. The scrolling headline bar would stutter along, sending CPU usage sky high. Also, as I scrolled down the page, pictures would also slow the scrolling speed to a crawl too, with CPU usage sky high again. I deleted my Firefox profile and this sped things up temporarily, but it inevitably slowed down again.
My new issue is Google Maps Street View sends my CPU usage through the roof. This definitely is Flash, and I have the latest version installed, so I don't know what the matter is with it. It's very slow and stuttery.

Are you using the latest Flash player? And if so is GPU acceleration enabled and are you using GFX drivers that support GPU acceleration for Flash 10.1? (version 10.1.102.64).

Yes, I have the latest version of Flash and nVidia drivers version 258.96, which states has support for GPU accelerated Flash.
Nobody was comparing anything to do with video playback at all until you came in. "rich content" != video. Far from it. Video is video, rich content is animated elements, or even just coloured and styled elements.
Vapid response? Again you've shown us you don't bother reading. Just look through those links in the search results I've posted, as well as the rest of my post for reasons. Oh and lose the better-than-thou attitude. This is a discussion board and *every* time you enter any discussion you always have an aggressive attitude and immediately turn it into an argument. No doubt you'll quote this with something "www is poor petal a little bit sensitive and getting upset? I can't be responsible for other people's fragile feelings." Despite you posting in such a provoking manner delibrately to try and get up people's noses and assert yourself over others.
Actually Flash has been GPU accelerated by default for a while - and is normally the delivery platform of choice when it comes down to performance anyhow. Hence why you don't see many javascript based games, but tons of flash ones.
However as has been mentioned - GPU accelerated JS engines are being adopted, notably in upcoming firefox, current chrome and [shudder] the "new" IE9...
Checked both websites you mentioned - and they both feature a combination of javascript driven and flash generated elements. Perhaps its the combination of both that is illustrating how much the two combined can suck up CPU power and then demonstrate it perfectly with juddery playback.

Using Chrome seems to fix the performance issues with Flash.
