I,m in the same boat. I,ve ran SLI quite a bit. Just about bought the DFI DK 790FX M2RS but cant make up my mind if I want to run SLI or Crossfire in the future. Putting it off for a little while, Nvidia is suppost to release there AM2+ chips when the Phenom with the B3 stepping and the tri cores are released. I think when the L3 bug was found on the Phenom that nvidia thought they would not sale enough so they just put it off till AMD fixed the Phenom. How do you like the MA770, thinking about getting one for my second computer?
