Pc building help

Trying to build my first pc and I main use of it is to play games at most 1440 p with high fps and also record gameplays prioritize 1080p

So I was trying to save money on ram I came across klevv bolt ddr5 6000 cl 30 and Klevv crass vrgb ddr5 6400 cl30 Significantly cheaper than other brands.

The question is will these work/ have any issues with 9950x3d or 9800x3d Along with Gigabyte X870 AORUS ELITE WIFI7 ICE ATX AM5 Motherboard Also getting 9070xt graphics card

Any other advice I where I should go from here based on what I have or intended use of the pc would be much appreciated
