i want a 1440p gaming monitor. i d know that the samsung one has g-sync, but im unsure if that is worth it, because i want an ultrawide monitor. i am willing to go with standard 2560x1440, but i would rather have the wider display. i want to keep it under around $250, and i am open to other recommendations. that you!
