I put another 8800GT in my pc today, hooked up the power cables, started pc, installed drivers, rebooted a few times.. and finally ran 3dmark05. My 3dm05 score went from 19700 -> 21590. Then i tried NFS Pro Street, 8xAA, 1920x1200, everything max. This time with fraps. It shows about 195fps in menu and 30fps when at race event or on track. Then turned off SLI in nvidia control panel, started the game and ~190fps in menu and 30fps in race/event stage. Same situation in Fallout 3. FPS at 1920x1200 with 4xAA, 12xAF, custom (slightely below ultra) settings. SLI=37 fps, SingleGPU=38 fps. I'm using 178.24 whql drivers, nvidia recommended SLI (no manual AFR/SFR), all nvidia options default. Winxp sp3. Should mention that the new card is Msi 8800GT Zilent OC (running at 660mhz core, 1900mhz mem) set as primary.
