I forgot to mention the PPD dropped about 15k to 20k a day.
It went from 75k to 80k a day, to 60k.
A few hundred I would not worry about, but that is WAY too much to tolerate.
Will go back to previous client and see if the PPD goes back up.
It might just be the work units you've been getting or some setting in the configuration... I've been using the newer version on all my Fermi cards and the PPD hasn't changed... Did you have the Core priority set to slightly higher and the "do Not lock to specific cpu" checked? Not sure if these settings make that much of a difference but that's what I use (I'm also running smp on the cpu's)
Might want to try FAH gpu tracker. Sets up pretty much everything for you, and it's been what i used in last year or so. No problem, apart of priority managing (cpu idle and gpus below normal). Since i found those settings, everything is optimal ppd wise. No variation (except for the 9xx vs 5187 wu ppd difference) in ppd in one year. Pretty stable if you ask me!
