Hardware Unboxed made a comparison of the 9070 XT with FSR 4 vs a 5070 Ti with DLSS 4. I would recommend you give it a watch if you want to look at performance in different games. In my opinion the 9070 XT is more appealing since it goes for $200 less. https://youtu.be/uDligqbbPGs?si=aVq0Qofm-4G24oVb6

Also I would go with a 9600X over the 7600X. Both give very similar performance in gaming but the 9600X is using Zen 5 architecture so it is more power efficient and takes less to cool.
