Any suggested changes of PC build?

https://au.pcpartpicker.com/list/WwVYQd

I primarily do AI stuff (reinforcement learning, image generation etc), 3d stuff using Blender/Maya, Game Engine use as well as gaming every now and again. The 5090 is obviously easy as I've been waiting for it to upgrade but for cpu is there any reason to go AMD? As for ram higher speeds are better than timings for things like AI? I'm not looking to overclock the ram.

Just want to make sure there isn't anything that would fit my use case better.

Thanks
