Okay, slow with that post. So you are actually running the same drivers. I experience a very
noticable  boost in poser when SLI is enabled (like greesed ligtning) One thing that comes
to mind is your motherboard. If both PCIe slots are x16, if you board is SLI certified it'll have
dual x16 slots. And in the bios is the settings set correctly. Now, where are you connecting your
monitors DVI connector? Should be on the top card (slot1 card) on the connector closest to
the edge of you case. That's monitor 1 connection. For settings in ntune, that can be
cumbersome, there is so many to set or change rather. Forget if I set this or if it's default,
the anistropic filtering to application control. It's a performance and qualilty setting, the rest in
that little menu I have set to highest values.
