Get a 1080 , 1080ti or atleast 1070 for a good gaming experience
Ehhh, I would scratch a 1070 out of the picture. 1440 at over 100 fps is pretty difficult even with older games on the highest settings. I would just strictly stick with either the 1080 ti, rtx, 2070, or the rtx 2080. I feel like there should be a little wiggle room for higher fps with a better card.
