Dual Monitor diffrent hz??

[Chompski]

I had question. I just recently bought an 144hz monitor, my old one was 60hz and i was planning use both at the same time. Is it possible or it will bottleneck my 144hz into 60hz? Im using GTX 970

You can run two monitors at different refresh rates without any kind of difficulty or added stress to the graphics card.
