Looking for a new gaming monitor. Any suggestions?

my dell tn panel has been doing me well for the past few years, but it's so washed out and gray. I'd love to see if I can get an IPS or mini led monitor. I'm looking for something that works with gsync, is 1440p, 165hz (180 will be a plus), and potentially have the hdmi inputs support 4k (from a game console or a scaler). is there anything that can do all this at a good price? my budget is around $300 but I could go a little higher (or lower)
