First build for gaming (looking at 1440p with intent to move upto a 4k monitor eventually)

Hi all, as the title says it's my first build. I've acquired all the parts now, but thought it was worth showing the community for any advice. I'm aware the x870 is overkill but I initially had a b850 in there but the x870 was £10 cheaper so I though why not. I'm assuming the x870 issues with sharing pcie lanes won't affect me if I never play. To use more than two SSDs?

I'm using a iiyama GB3290QSU and will be happy at 1440p for a while given the pc climate but would eventually like to go 4k oled - does this build future proof me enough?
