Seems like a fair price, I have the Acer XB270HU and it's phenomenal. Your sources are definitely right, GSYNC/Freesync really makes the difference but there's one catch I instantly see with that monitor, and that its a TN panel. TN is just absolutely disgusting, if you've ever used an IPS panel and then went back to TN you'll know what I mean. Considering the price however, I might be tempted... hmm.
