TheTheory :
I play CS:GO a lot so I might notice the difference. I have a 1060 EVGA card. Budget is under 600 if possible. Is there not a good monitor that has very good response time but also could be watched at 2k at lower HZ?
If you want to watch anything at native 2k, you need a 2k monitor. Sounds like a 1440p, 144hz monitor with Gsync is what you're looking for.
