the gtx 1080 supports G Sync?



i know u need a g sync monitor for that,but the card need to support it too right?
 
Gsync hardware is in the monitor itself, not the card. I believe compatibility for all nvidia cards goes back several generations to like the 4xx series at least.

I'm using a 1440p gsync monitor at 144hz and I will never not use adaptive refresh rate ever again.
