So i recently bought a new 1440p monitor @144hz but i have an old 1080p 60hz monitor that i want to use the 1440p monitor would be for gaming while the 1080p one would be for discord and other things the 1440p is currently connected with a dp port my 1080p monitor has dvi port i have a gtx 1070 that has the ports necessary to connect both monitors would this work and/or would there be any problems with this?

I was looking into getting a new monitor and I found a 1440p monitor that supports 100hz but only with displayport but my laptop only has a mini displayport, hdmi, and thunderbolt 3. would any of the ports be able to output 100hz if I got an adapter to display port?

what would you recommend?

Is this PSU good and is it enough for gtx 1080ti

I have a friend that's willing to let me buy a new 1080 from him at MSRP so should i sell my 1060 and get it now or should i wait for next gen graphics cards to come out
