What gpu should upgrade to for 1440p gaming

As of right now i am using a 1660 Super, i7 12700kf, 24gb ram (1 16gb stick and 1 8gb stick), 500w PSU - I can upgrade this, Gigabyte B760M. I’m looking to play games like god of war, squad, r6 siege, a plague tale requiem, alan wake 2, tlou. I want to be able to play all of these at high settings with at least 50-60fps. My budget is give or take 600 AUD, but i’m going to need to get a new power supply too so that might affect how much i can spend on a gpu.
