PCIe 3.0 vs PCIe 4.0?

[andremiles]

I am trying to decide in between two mobos that are on sale on a good price: B450M Steel Legend vs B550M Aorus Elite. Steel Legend is the cheaper one.
I am thinking of upgrading my rig and I am choosing a Ryzen 7 5700X and a RX 6750 XT (both on sale with good prices as well). I am not planning going above 3200mhz on RAM. I am planning on using my PC for mainly video editing + recording/streaming.
My question is: The true advantage I see in choosing the Aorus Elite is PCIe Gen 4... But aesthetically, the Steel Legend looks better and, as I said, is cheaper. I need advice and clarification on that.
Thank you!

You will do video editing with 6750XT? Might want to consider Nvidia GPUs, unless your software does better with AMD.

And PCIE Gen 3 or 4 only matter when your GPU is faster than 3090 Ti or the GPU PCIE interface is not x16, so with 6750XT, there shouldn't be any problem.

Thanks for your clarification!
