will both video card( on board and external video card) will be shown on the device manager when hybrid SLI is activated? BTW what video card series does xfx 8200 mobo supports on hybrid SLI?

Yeah I know on board has nothing to do with the SLI , my question is about "hybrid SLI" where if the pc is in idle state it will just use the onboard for energy conservation, then it will just switch into the PCIE card when the running apps requires more computing muscle in graphics ^^ . I think you mean "SLI" which more than one video cards are on PCIE slots ^^ . my question is if the hybrid SLI is enabled in bios both onboard and external card will be shown on the device manager. .

If the hybrid SLI is enabled in bios, both onboard and external card will be shown on the device manager. But it only work in Vista, not XP..
