Windows Vista Performance on P1610

How does a half-size PC perform, you ask? Let's find out what Windows Vista thinks of the setup:

Original score: 2.0 {2.7,2.9,2.0,2.4,3.7}

Re-test today: 2.4 {2.7,2.9,3.8,2.4,3.7}

I wonder what was behind the jump in perf between Setup and now... perhaps it was just busy, or there's been a driver update?
