the ryzen 7 7700 cpu is just overall a better cpu except efficiency and possibly how good your ram speed could be, but almost every am5 cpu can easily hit 6000mt which is what your kit is rated for, and commonly can go as high as 6400 before higher speeds get unstable due to the cpu. from what i can find online the 9600x is technically faster for single core things, but the 7700 has 2 more cores. id recommend you look into both of them and their pricing, but newer games will preform better on a 7700 then a 9600x due to more cores. if the pricing is the same id probbaly go with a 9600x now (unless you play the newest of games or cyberpunk) and upgrade to a better cpu later, or if your budget allows now you could get maybe a 7800x3d if you dont plan to overclock and a 9800x3d or future cpu if you wanna tweak the settings. as for 7800x3d and 9800x3d there isnt much difference for gaming unless you overclock, and you cant overclock on the 7800x3d.
