If you go for a TN 27" i would reconsider if you think you'll notice pixel inversion in games, that's why i ended up getting the 24" Dell screen instead because it doesn't have that issue.
If you're happy with IPS i don't see why not, I'd do some in depth comparisons before choosing but that's just meSo would the Acer, AOC, Asus (IPS) be the better choice?
