I agree with earlier posts that it is all very relative.
A detailed scrutiny at all test results shows a general consensus that is:
- the K-7 RAW files are as good as any other dSLRs incl. the K-x at high ISO,
- the K-7 JPEG files at ISO 6400 appear not as "good" as K-x JPEG files at same ISO,
- the K-7 outperforms most dSLRs incl. the K-x at lower ISO.
One issue is the notion of 'high ISO'. We should be talking about low-light performances. I would stress therefore that the discussion is meaningless because any 'conclusion' depends very much upon the lens:
a good glass is more important than the camera body. We should compare apples and apples
With my K-7 and Voigtlander Notkon 58m f1.4, I can take great photographs in low-light, that most Canikons and the K-x with their respective kit lens could not shoot. If I was using this example, I would conclude that my K-7 outperforms the Canikons and the K-x in low-light ... Off course we know that this conclusion is silly, pointless.
In summary, the K-7 is a great camera. Just look at the users' reviews:

It has an excellent AF for low-light conditions
If you are interested into low-light shooting, consider to buy a fast prime lens with large aperture. Pentax has some of the best fast primes in the market, all brands together. There are also some excellent 3rd party fast primes lenses (Voigtlander, Carl Zeiss).
Hope that the comments will help...
