I got 2 main questions here:
1. Am I right on the money with the RAM here? I am still new to DDR5 so I was wondering what is the DDR5 sweet spot equivalent of the 3,200 & 3,600 MHz. Aim is good speed but more importantly stable.
2. There's also a little headroom for upgrade here and he's thinking of either upgrading to a 14700k or to a 4070. Not sure, which one is worth while if he had to pick one.

Other than that. Any recomendations are appreciated
