I am not really worried about getting up to 144hz. I am getting a pretty good pc soon and it will handle 3440 x 1440 easy. I think 2560x1440 would be fine but I just say this monitor on craigslist and thought it was a good deal. I have been looking for a monitor for a while now.
Grab it then id recommend a 2560x1440 but its your choice
Yeah I don't know i'll think about it don't want to get it right away a regret it later.
