3870 wasn't really on par with the 8800GT though. In Cryengine 2 it was around a 25% difference. Also, I somehow doubt AMD has been keeping up with driver support for said old card. That was always one of my primary complaints about ATi.
Could also be an issue where running in CF actually makes the game run slower. I would like you to remember though that the ATi 3850 is the bare minimum requirement for this game, so it's heavily plausible that your card when running in single gpu mode just doesn't cut the mustard for this title.
