If you're coming from 1440p or 4k I wouldn't recommend it. I went from 4k 144hz and definitely noticed an increase in smoothness but not sure if the quality loss is worth the idea. The best I can compare to is 1080p without glasses. 4k is like 20-20 vision after lasik lmao. If you're already running 1080p 144Hz, this is 100% worth the money and a real upgrade for you.
