So I've had my desktop for over 3-4 years now and I want to get a new graphics card. I'm wondering if it's okay to use 2 graphic cards because I don't want to throw away my current one. Any advice would be appreciated as I don't know how these things work.
Right now my current graphics card is a Quadro 4000. I was looking at the Nvidia GeForce GTX 960. Is there something I need to know if you have to find something compatible? Thank you as I am completely clueless
