Funny that you say it doesn't hold a candle...the low light performance (pulling a black cat out of a black underexposed image) is something the D300 simply can't do since it uses a Sony sensor that is a generation back.
You also don't say what you're using it for? For AF, the D300 is no doubt better. For doing art nudes like your avatar, I'd say the K-5 would do better. I do studio work w/ the K20D and I'm still fine with it, but low key has too much chroma noise...which isn't noticeable at web resolution, but only if you pixel peep. The K-5 is far ahead of that and will probably do fine against the D300 for studio work...
The K-5 is a no brainer if you're going for small and low quality...it's not much bigger than the 4/3rd cameras...
