SMP will really help your progress on getting the first million
I have found it to be resonably stable on my dedicated folding rigs. I run dual boot on them so i can fold win or linux smp but atm I run mostly linux (~ 14 out of 16). If the wu mix changes (ie. ppd) significantly between them i can fairly easily switch over.
FahMon is pretty good for monitoring them but it does take a regular manual scroll thru its log view to ensure none are 'hung'. Since i run 6 quads in linux with 2 instances, if one instace does hang for a while it just means the other one goes faster, so i don't see much of a drop in production. The dual cores with single instances do need a bit more watching since it is easy to lose 1/2 day of production. I also need to watch that i don't let 2 2608/09's run at the same time on the quads since ppd and elapsed time will degrade noticably.
But still, all the more reason to have more quads
