As usual the differences are a lot more difficult to see at ISO 800, with noise once again the great leveler. That said, the SD870 IS has better material to start with, and the output is visibly more detailed and really not that bad for ISO 800 at all. Although we'd expect an 8mp sensor to produce more noise than a 7.1mp one, the SD870 IS performs well against its predecessor too. As we've seen with most recent Canon models the noise reduction is applied with a fairly light touch (particularly on luminance noise), meaning the images look grainy, but have a far less 'processed' look than many competitors, and retain more detail. Whether this is a good thing or not is up to you; we'd rather have the option to remove the noise ourselves than be stuck with excessive NR.
