Upgraded to a 165hz G-Sync panel recently and it was a revelation after running at a v-synced 60hz for years and years.
Order the 1080TI about a week later as the 970 I had wasn't cutting it at 1440p.
I actually find most modern games run at about 90-110fps with what I would consider "good settings".
Even if you turn settings way down 165 is really hard to maintain.
