just got a new 1440p monitor, i think need some advice

I need some advice on my PC setup. i just got this nice monitor, the screen is crisp and clear, 1440p with 75Mhz.

Ok so there's something you have to keep in mind when you're going high res. Rendering load goes up exponentially with screensize. What can be overkill for 1080p can be inadequate for 1440p and utterly unplayable were you to consider 4k or such.

That being said, a 1080ti is plenty for 1440p on current gen games. 2000 series would be overkill. Going less than the 1080ti... is a bit borderline. Research specific benchmarks for the game and screen resolution you want on the card you're considering. That will tell you if it's 'enough'.
