@sadaharu keep the mobo. You can upgrade 3300X or better if you have extra cash. I dont say you should upgrade 3300X but it even beats your current CPU on gaming. Seems you have b-die memory you could run it easily >3600 MHz with 3000-series. Heat not be issue but if you have problems you can always add more fans and I recommend Arctic P12 and P14 fans. They are good as Noctua's fans less than half the price. Also Arctic have new AIO liquid cooling that beats everything. Anyway AM4 is dead end socket. 5000-series is fast on gaming but not really worth the price and hassle if have a good motherboard and not 400-series.
