Had my eyes on the z790 Carbon WiFi for a while now but have a problem when it comes to the M.2 shields. Just got this and it's not going to fit unless I leave a shield off but it's not so simple. I'm wondering which of the z790 range is worth getting vs z690, I'm getting the 12900k and thought I should probably go for DDR5. Also, the PC is not for gaming as I'm mainly using Unreal Engine 5 and Blender.
