Default SLI/MultiGPU drop FPS

Hi , thas week i get a 9800GX2 , i run first time with monogpu ( nvidia-settings say screen 0 gpu--> 9800GX2 GPU0 )
2 time i see the doc ( chapter 25 ) and make new xorg.conf with nvidia-xconfig --multigpu=on but after restart X i have realy poor fps ... I keep see the doc and fine more info with nvidia-xconfig --advanced-help , i fine some "tricks"
