Is this a crop from the original image, or did you resample the original image down to 1024x768 to get it to fit the forum?
If you resampled the image, then you've effectively processed some of the noise out of the image.. The best way to show noise is to do a straight crop and post that.
That's true, if you want to zoom in closer than you'd ever actually view the image and nitpick about the noise you're bound to find...
Or you can look at the image at a more realistic scale and not see much or any noise.
OP, the "Poor High ISO Performance" threads are ridiculous... 7D images are usable about a stop higher ISO than 40D or 50D... period. 5DII are good for about another full stop on top of that.
People need to make actual prints or look at the images in sizes and resolutions that they'll actually be displayed online, rather than zooming in to 100%. If you magnify any image enough, it will start to fall apart and give you something to whine about in forum postings, if that's what someone really wants to do.
