Hi, im looking to purchase a R9 290X for my computer, i already have a gtx 760, i need the r9 290x so i can dogecoin/bitcoin mine. Is there any way i can have both plugged in but not both running at the same time (I know thats impossible.) I dont want the power of both at the same time. Is there any way i can just have a switch or go into the bios and switch the current active one. I need to have both sloted, but only one at a time active.
