Playing on LG TV 77” 144hz using AMD RX 9060 XT 16gb and considering selling it and upgrading to 5070 Ti 16gb… is it worth it for 4k?

Pretty much as the title say.

At the time of purchase I didn’t know about 128bit memory bus not being compatible with 4k TV with 144hz.

What do you think? Is it worth it for single player games with good graphics?
