Not sure why that happened, but as you can see above, I graphed out the FPS over the Mafia 2 bench run (1920x1200, maxed out in-game) using FRAPS, and posted my results above.
My results show that, at least at these settings, there is a definite benefit to adding an 8800GT to my SLI 470's, esp. in the first 1/2 of the benchmark. It seems unlikely that a 570 would experience less of a benefit from a 9800GTX than my 470's do with an 8800GT. Assuming all else was equal, of course.
I've also played part of the game with and w/o the dedicated physX card, and the dedicated card provides a noticeably smoother gameplay experience.Edited by brettjv - 6/12/11 at 9:44am
