In the market recently for a big monitor with high framerate and gsync and this seems to be a pretty good deal. Reviews seem to think it's pretty decent quality despite being a tn panel, and from the little bit I've played with it since it arrived I'd have to agree.
Good thing about the Dell gaming monitors is you can get gaming specs without the monitor looking like it should be sitting in your mum's basement.
I would have picked up this:

For $796
Or this:
https://www.ebay.com.au/itm/Acer-Predator-XB1-XB271HU-27-WQH…
For $827
Both 144-165Hz G-Sync displays but IPS so better viewing angles etc.
