Minecraft is CPU bound game, the GPU has little impact in your performance.
It's monitor and the cable you are using to connect your gpu and monitor. If your monitor is 60hz, then you won't be able to receive more than 60 fps. On 120hz or higher screens, one need to use hdmi, dual-dvi and display port cable to achieve the goal more fps. Either way, hz of your monitor can also limit your fps.
