Thanks for the updated info. The 6700k is a very nice CPU. What speed is your RAM? Last but not least, whats your screen size preference/limitations? I have the 1440p version of #1 & love it. Freesync is nice. It works great with my 1060 6GB.
Here are a few ideas:
#1 - MSI, 165hz, 32", 1ms response, curved screen, Freesync & 1080p, - $306
#2 - ASUS, 144hz, 24", 1ms response, 1080p - $199
#3 - AOC, 144hz, 27", 1ms response, curved screen, Freesync & 1440p, - $249
