Well, I am unfamiliar with the availability of new and used video cards in your region.
However, the hierarchy chart (http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html) will give you a good idea of what video cards will perform equal to or better than your old one.
Generally the 1050Ti (or equivalent performers) is considered the starting point for 1920x1080 if you are willing to turn the details down somewhat. But, if your R7 265 was performing to your needs, then anything on that level or higher should work for you.
The market for new graphics cards is pretty crazy and overpriced these days, though.
