best gpu upgrade for Ryzen 5600?

Currently have a Ryzen 5 5600 with a 2060 super and a 650w psu. I was thinking about upgrading my gpu as I just got an Odyssey g9 (32:9 1440p 240hz). I don't wanna overpay for a card that my CPU can't handle. Id like to keep the same psu but with how power hunger cards seem nowadays, I'm not against selling this one and getting a higher wattage supply. There's no set budget, just looking to see what pairs the best. Thanks!
