Upgrade B760 -> Z790 ?

Hi Guys, good holidays to y’all. Today i’m here to ask if to spend my Christmas money or not🤣

So basically i got some time ago my i5 13600K on my B760 Gaming X. I was wondering if it’s worth and useful (so if I would notice any difference or something) upgrading to a new mobo (that would also be overclockable or anyway not undervolted) and DDR5 to exploit better the power of my components. Consider that in the future i would like to upgrade to RTX 5000 series (but not now in 2025), and that for now I use the PC for gaming (also triple AAA) and I would like to start make streams.

Build: - B760 Gaming X DDR4 - RTX 4070S MSI Ventus 2x - DDR4 RAM 32 GB (16x2) - i5 13600K 13th Gen - PSU 650 watt - Air cooling (Thermalright PA for CPU, neutral airflow with 3 intake and 3 outake fans)

Let me know what you think about it!
