Kevin: looking forward to seeing your results.
It seems like the Corsair XMS3200 C2 is going to be my choice. Seems like there are various opinions about the mobos, but I don't see anyone recommending/pushing anything else than Asus or Epox. I think I'll stick with Asus for now.
I didn't see any comments on what to do about the PCI clock issue, nor have I seen anyone that has run 200 FSB, except for overly-giddy Brad
