Well, two 430s are now folding away and PPD is stacking up nicely - though had to set the CPU usage to 65% as that Athlon just isn't up to loading a browser up and folding without stuttering.
Because of the heatsink was too big for one in the ITX rig but the 7900GS is a nice single slot replacement for the E-350s 6310 - 6310 keeps losing it's progress for no reason too, can't be bothered with it anymore so just removed the slot.
EDIT: PPD = 8500 - 9100 @830/ 1660/ 900
