I plan to get a 2K resolution monitor for gaming purposes in the next months, once the new R9 series is out (if everything goes as expected), but im quite confused by the differences in the resolutions of most monitors and not sure if its really worth the price. What is the best 2560x monitor for gaming? x1080, x1440 or x1600? Is there a big visual/detail difference any of them and a generic 1920x1080 monitor that I already own?
