So I've been wanting to buy a second monitor but didn't know if my graphics card would be able to handle it. I have a GTX 960, Intel core i7 4790K 4ghz, 16GB of RAM and a 1080p 60hz monitor. If I get a 144hz 1080p monitor will I be able to use them both or will I have to upgrade my GPU? I mainly play Minecraft, CS:GO, Destiny 2 and Geometry Dash
