I wanted to just ask the pro's on here how to setup an SLI configuration for two GTX 970's, aftermarket ACX cooler versions. Once I put the second card in and attach the SLI bridge, do I need to install drivers for both cards, or will one driver setup suffice for both? Is there a place where I turn SLI on / off while on the desktop, or is that located in the Nvidia panel? And if there is anything else you think I should be aware of, please let me know. I'm pretty sure I'll be fine with my psu. It's a 750W gold Antec Truepower Classic. I did the worst case scenario on wattage calculator and it suggested a 680watt psu, so I think I should be fine.
