I have an EVGA Nvidia GeForce GTX 760 which I bought a few years ago and an Zotac Geforce GTX 970 which was recently given to me by a friend who upgraded his GPU. I would like to know 1. If I can use both GPUs in my computer, and 2. If so how I might go about doing it. I've read conflicting reports of people saying that different GPUs could be put in an SLI bridge.
