Poor gtx 295 performance

[pwolfe]

Is there anything special I need to be enabling in my xorg.conf to get better performance out of this card? I'm getting lower glxgears and nexuiz fps than with my 8800gt

I am currently using the 185 drivers as I hoped that would improve my fps. I am attaching my xorg.conf

You have to enable SLI also: Option "SLI" "true" (maybe option "SLI" "AFR")
Have a look in to your xorg logs, there might be some useful information to your problem: /var/log/Xorg.0.log

Check this nvidias manual also:

I have enabled sli, but I see no discernable performance increase.

Hmm I don't have any clue of multigpu solutions. That log would be usefull, but maybe it's best that you ask it straight from developers:
