With the 2 GPUs and the hex folding -bigadv (which it should just about manage with the 2 NVidia cards) you should have a very nice setup there, and it should cost less than 100W more than your current rig (and you'll have some money in the bank after selling the quad too).
This is the PSU I'm looking at:
It'd mean I wouldn't have to worry about upgrading it again.
As for the rest, the Q6600 will go in the family computer, and I might keep the 9800GT in there for constant Folding; if it makes too much noise, I'll probably take it out and only bring it in for Foldathons/events.
Hard drives and CD/DVD drive will still be needed though, so all I'll be left with is a Dell case and motherboard, and my current PSU.
