The predator OC's to 100Hz. I have the G-sync version (my work laptop has an nvidia as well).
I've heard great things about 144hz monitors, but no 1st hand experience. I LOVE the predator though.
That 980M has got to have something decent for an output. I know it defeats the purpose a bit, but buy a decent monitor and connect?
All of my outputs are DP. Just think that most of what I buy ends up being business/monitor expectations instead of homeline/TV.
I bought the Samsung for it's response time (

HMU if you ever have any questions. I love this stuff =)
