Hi, Whilst not willing to pull the plug quite yet on my 5.1 (3.46, 680 Mac Edition, 24GB RAM) I'm interested in adding a second card for windows whilst under Bootcamp. Having read the forum I've settled on getting an external PS just for this card, so there shouldn't be any power concerns. My wish is to retain the official 680 Mac edition to drive my two monitors whilst in MacOS but load the newer, likely 1080 or 1080ti for use in Windows (to use the same monitors via different inputs). Is this achievable? Would I have to load OS then choose Bootcamp via the shutdown menu? How would I tell the system to run the new card on reboot or at the boot screen? Would I have to install extra drivers? I'm aware there aren't any native drivers for the Nvidia 10x series, partly the reason why I'm not parting with the 680. Thanks for your help!
