For just 50 dollar more, 4070 Super is faster at 1080p/1440p and equal at 4K...... and much faster when using RT
4070 Super also have better performance per watt, and more features (like DLSS).. Upscalling is becoming necessarily for Unreal Engine 5 games because UE5 titles are too demanding
Also, even though 7900GRE is equal at 4K, many game don't run well on native 4K which means you have to use upscalling to get 60fps and Nvidia has better upscalling tech.... In many cases, even DLSS balanced mode match or beat FSR quality mode
In other words, 4070 Super is better to buy..... 50 extra dollar is noting.
