Technically speaking the X2 4200+ would be slower overall than a single core 3200+, and whilst the OS (at last !) may play happier with a dual core, from the strict hardware PoV the overall lower clock speed of the 4200+ may be a cause of the discrepancy, because of slower overall CPU to RAM I/O.
This is BTW the first hard evidence I've seen to support my theory that dual core CPUs actually have certain disadvantages (in Vista) compared to the faster single core chips of the same generation.
One should remember that dual core CPU technology was originally invented as a means to gain more clock cycles per CPU for use with Windows XP.
It would seem that (in Vista) this extra CPU activity and lower overall CPU clock speed may each contribute to lowering RAM I/O from the CPU. Not good
