Something is definitely up.
My core 2 duo's generally run between 2200 - 3300 ppd running on SMP- 2 so your 6 banger should easily outpace me.
That quad core with hyper threading for a total of 8 cores that BAP has should be a monster as well.
I'm a little surprised that the 465 doesn't do more.
My 460's do what your 465 is doing and then some.
2d clocking is usually the culprit when my gpu's start acting up. Easy way to tell is look at the temp of the GPU. If it is in the 50's it is 2D clocking. The 460's usually run in the mid 60's and into the seventies and eighties.
So that is another thing you could keep an eye on .
Let us know if there is someting we can do to assist Mark.
the best,
