Thanks that is great info really appreciate it, and for explaining it out, I didn't know that.
So if I understand it right
The x670e Pro RS has 1 5x16 slot ( not sure how many lanes) 1 m2 5x4 and 1 m2 4x4 slots on the main chip
the x670e Steel legend has 1 5x16/8 slot 1 m2 5x4 and 1 m2 3x4 on the main chip then 1 m2 4x4 on the 1st chip, you'd think they would have those m2 3x4 and 4x4 slots switched
So looking at that I think the Pro RS has the edge
however The Pro RS has a 14+2+1 Power Phase, 60A with 1x8 and 1x4 power connector
The steel legend has a 16+2+1 Power Phase, 60A with 2 1x8 power connectors with Nichicon 12K Black Caps (100% Japan made high quality conductive polymer capacitors
Do put any stock or thoughts into that, I feel both should be ample anyhow
