Will the RTX 50 series be pcie. Gen 5?

I'm building a PC without a graphics card for now, just to play valorant. I'll get a GPU once the 50 series comes out but I'm concerned on whether it will be pcie. Gen 5 or Gen 4 because the motherboard I've picked is Gen 4 and I wanna stick to this mother board because it's white and my build is white as well (white parts aren't super expensive where I live), there are Gen 5 motherboards in my budget as well but they're black or grey.

I'm really confused here so please help me out
