looking for a good G-sync monitor

Solution
all GSYNC: https://pcpartpicker.com/products/monitor/#A=1

1) OVERBUDGET choice: https://pcpartpicker.com/product/ttnG3C/acer-monitor-xb271hubmiprz

I'm still listing that because it gets you the goodies at $630 (plus tax/ship)
IPS,
165Hz
2560x1440
GSYNC
27"

2) https://pcpartpicker.com/product/MTkwrH/acer-predator-xb1-270-2560x1440-165hz-monitor-umhx1aaa01

That's only $530 but you get a TN panel instead so the color isn't quite as good and off-angle viewing will tend to be off even more but a good TN panel isn't bad per say just not as good as a good IPS panel.

3) $400

and

Now...

and

Now in addition to TN panels you're dropping to only 24" screens which is quite noticeably smaller than 27".

Summary:
Those are the main choices AFAIK.

If the budget is really tight around $500 then I'd get the 2nd choice (TN panel).
